What Makes Java 14 Special?

Java 14 has finally been released in March 2020 and brings a whole host of new features that will help ease coding frustrations.

In this article, we will break down the top 6 features that make Java 14 an outstanding update compared to the previous versions. Here we go:

1. Switch Expressions

Although Switch Expressions was just a preview feature over the previous two versions, it has now been given permanent status in version 14.

The lambda syntax was introduced for switch expressions in Java 12 and this means that multiple case labels for pattern matching could be produced. This also stopped any fall-through that led to verbose code and enforced exhaustive cases that would issue a compilation error if all input cases weren’t entered.

In the previous versions yield statements were introduced to replace a break for returning values from an expression. Within Java 14, all these features are included as standard now. We should also point out that yield is not a new keyword for Java and is just used within switch expressions.

2. Previewing Text Blocks

Another former preview item, Text Blocks were first added into Java 13 with the intention to make multiline string literals much easier to create. In particular, HTML, JSON and SWL query strings became much easier as a result.

“Text blocks do remain a preview within Java 14, but they have some interesting new additions,” says Robert Class, a journalist at NextCoursework and Australia2Write. “In particular, you can now use a backslash to display smart multiline string blocks.”

The code \s can build trailing spaces that are ignored by the compiler as a default. This then preserves all of the spaces that are included before it.

3. Pattern Matching for instanceof

Most codebase creations by Java developers will include a strong use of instanceof conditions filtered in throughout the code. Generally speaking, the instanceof conditional check normally comes before an explicit typecast.

Within the Java 14, developers will be happy to know that this has been removed to make conditional extraction a lot clearer. The scope of this variable is currently limited to just the conditional block.

4. Useful NullPointerExceptions

Most developers will tell you that the null pointer exceptions have been a complete nightmare in previous versions of Java. The infamous NPEs can be exceedingly difficult to debug.

This invariably led to developers falling back on other debugging tools or trying to manually figure the variable/method that was null because the stack trace shows only the line number.

“In Java 14, we also see the introduction of a brand new JVM feature, which has enhanced insights with a descriptive stack,” suggests Anita Lockfield, a tech writer at Britstudent and Write My X. “This is not a language feature, but a development of the runtime environment.”

5. Previewing Records

Within Java, you can build classes to hold data and utilize encapsulation to control the way that the data is accessed and modified. It is an object-oriented language.

Because it uses objects, this makes manipulating complicated data types easy and straightforward. This is one of the things that makes Java popular as a platform. The problem has been that the creation of data types has been verbose in old versions and it needs a lot of code for even the simplest case.

Within Java 14, they have introduced records as a brand-new preview feature. This new concept helps developers to include a new language feature without having to make it part of the Java standard. This means that developers can test features and provide feedback that leads to changes before those features become standard.

If you want to use the preview feature, you need to specify the command line flag, --enable-preview for the compilation and runtime. For compilation, you must also specify the sourceflag. The record becomes a much simpler way of showing a data class.

6. New APIs

There are three new APIs within Java 14 that we love. The first is java.io which contains a new annotation type called Serial. This was designed to be used with compiler checks on Serializations. This means that annotations of this type can be applied to serialization related methods and with the fields in any classes declared to be Serializable.

The second API that we enjoyed is java.lang. This class has two distinct methods for the new Record feature, including isRecord() and getRecordComponents(). These have a range of RecordComponent objects and gives up to eleven ways to retrieve things, like the details of annotations and the generic type.

Finally, the new java.util.concurrent.locks API has one new method called setCurrentBlocker. This provides an ability to unpark and park a thread. This helps avoid the same problems that previous versions have had with the Thread.suspend and Thread.resume methods. You can also set the Object that will be returned by getBlocker with this new API, which can help when recalling the no-argument park method from a non-public object.

Top 10 Best Apps for Programmers 2020

When it comes to using programming languages, coders can make an easy choice. Python is the fastest growing language, but JavaScript is still the most popular one. A great programmer knows what language to focus on, depending on the projects they develop.

But what about other programming tools?

The language is not the only thing that you need to choose. There are too many software developing tools, so you might get confused comparing all their features. First and foremost, you need a code editor. But you also need apps that help you focus and fight procrastination. Let’s not forget collaboration in real time, which is an essential need of modern programming teams.

We have a list for you. It combines various tools that cover different aspects of a programmer’s work. We’ll list the best apps for developers at the moment.

Top 10 Apps for Developers

1. CodeRunner

A successful programming process starts with the choice of an editor. It has to be fast, and it should support multiple languages.

CodeRunner meets those standards. It’s a lightweight Mac app that supports 25+ languages, and lets you do your work in the fastest way possible. Its bracket management, auto-indenting, and code completion features are outstanding.

2. Todo.txt

Your list of programming tools needs an app that lets you plan tasks and update them as you go through the daily schedule.

Todo.txt is a simplistic app, without too many options, reminders, drop-downs, and additional features that aren’t necessary when you want to create a straightforward list of tasks. You’ll interact with it right from the command line. This may not be what a usual to-do app user would like, but it’s definitely something a programmer appreciates.

3. Marked

If you use Markdown for easy formatting, you need apps for programmers that let you see the styled version before its publication. Marked gives you that option.

In addition to the preview feature, it also gives you tools for simplifying your style, checking the grammar and spelling, lightening the word count, and achieving an optimal reading time for the visitor.

4. Appian

This list of apps for developers wouldn’t be complete without Appian – a tool that lets you develop perfect mobile apps. It makes app development as easy as it gets. According to the provider’s estimations it takes eight weeks from the idea development to the app’s completion with the use of this low-code tool.

Appian lets you achieve greater speed by automating processes and combining data from multiple sources.

5. Unity

This is one of the best 3D software developing tools on the market. It’s perfect for creating games, architecture and engineering projects, automotive models, and more.

Unity offers a great user manual, which the most popular apps for programmers often skip. With these complete lessons, you’ll easily learn how to use the tool to its full potential.

6. MusicForProgramming

A music platform is not the first idea that comes to mind when you search for the best apps for developers. However, MusicForProgramming is one of those essential tools that help you work in a focused environment.

Currently there are 59 playlists that are specifically designed as the perfect background to a coder’s working process.

It’s much better than creating your own playlists on YouTube. Let’s be honest: it would take a lot of time for you to create 59 different playlists. Plus, when you choose your own music, you’re too attached to some pieces, which can make you distracted.

7. RescueTime

Is there a programmer who has never burned out? It’s a common situation, which leads to procrastination, dissatisfaction, and more procrastination. RescueTime can prevent the delays that you make when you feel unmotivated to work. It records how much time you spend on different apps and sites.

The reality hit will be enough for you to get back to work… seriously.

8. iTerm2

Your Mac’s Terminal is one of the essential programming tools that you use. But do you feel like it’s stuck back in time? iTerm2 is a similar, but more advanced tool.

It lets you split a tab into multiple panes, so you’ll navigate through different sessions. It also has a convenient search feature, which will find parts of your code that you need to work on. It has an autocomplete function, mouseless copy feature, easily accessible paste history, and more.

9. Unicode Table

This is an outstanding searchable database for all the Unicode characters that you plan to use. It includes alphabets, math symbols, fancy letters, flowers, stars, emoji, hearts, and much more.

You will get Unicode, CSS, and HTML codes for each character that you plan to use.

10. Codeanywhere

Gone are the days when programming was considered to be solitary work. Nowadays, we all use collaborative apps for developers, which allow us to join forces and work on different parts of the code at the same time.

This is a simple code editor, which lets you work remotely from any location. You will connect with your team, and you’ll all make changes in the code in real time. The app manages to make that process NOT messy, since it easily lets you switch between versions and check out each change that was made.

Only Use the Apps That You Need

Since the choice of tools for programmers is so great, it’s easy to start using more apps than you need to.

You need only a few software developing tools and accompanying software to support your work. Anything beyond the essentials may clog up your work environment.

That’s why we listed tools in different categories. Even if you use all of them, they won’t collide with one another. Check them out, and use the ones that can help you enhance your workflow.

The Benefits of Obfuscating JavaScript with Node.js

JavaScript is arguably the programming language out there, and specifically in terms of client-side programming languages, there are few alternatives to match it. Obfuscation involves deliberately creating source or machine code that is difficult for humans to understand, protecting the integrity of the initial programmers’ code. Programmers may deliberately obscure their code to protect its purpose or the implicit values embedded in it. This is primarily done to prevent tampering and reverse engineering. However, it is also important for those who sell their code, it is, unfortunately, easily copied. Obfuscating your JavaScript via Node.js does not prevent your code being copied, but certainly makes in hardly readable. Security through obscurity. Not only that, but Node.js is a language deriving from JavaScript, making the learning curve quite intuitive. Below we’ll go through the benefits and method of obfuscating JavaScript with Node.js.

Installing The Right Obfuscator

In order to get started, you need to install the JavaScript Obfuscator. This must be done before any JS code can be obscured with Node.js, as the process is reliant on the JS obfuscator module. It’s a powerful tool, with a wide array of features ensuring security for your source code. Limitless restrictions, local machine compatible, no server-data exchange, and compatible primarily with es2015 and es2016 makes it an intuitive and essential tool in protecting your code.

The logic to obfuscate code is relatively simplistic. It is capable of creating an instance of the Module, from which it is possible for you to use the obfuscate method that expects as first argument the code that you want to obfuscate. Through a series of transformations your source code is transformed into something obscure, and very difficult to read.

Process Logic

Given the popularity of JavaScript, using Node.js makes sense – particularly if you have experience working with JS on front-end applications, you will have an easy time learning Node.js for your backend applications. This makes your working environment more efficient as you are continuing to work in a relatively familiar environment.

Web Developer, Kuan-Yin T’an, of Dissertation Writer and OXEssays, suggests, “it’s really important to ensure that your workflow is compliments by the tools your using. Wasting time with other languages is inefficient, particularly given the complimentary benefits of Node.js with JavaScript. The system offers a wide variety of tools making a programmer’s life much easier – and in the end, that will only increase your output.”

Performance Positives

It is true that you are sure to find some high-performance power from using Node.js, but is important to dive into why this is the case. Node.js reads JavaScript code via Google’s V8 JavaScript engine – this engine is vital as it compiles the JS code right into the machine code. Essentially the code is implemented quicker and with greater efficiency. Additionally, the speed by which the code is executed is facilitated because of the runtime environment is support from non-blocking I/O operations.

Alanis Truijens, tech writer for AustralianHelp and Urgent Assignment Help, was clear in her own assessment, “The simplest version I can give is that Node.js functions as a JS runtime environment that allows JS coding to be executed in a server-side environment. At its core, this is an open-source platform which increases flexibility to get things done”.

Application Scalability

Using Node.js means that scaling your applications is relatively straight forward. Whether it is horizontal or vertical, it doesn’t matter, you can scale to your own needs. Additionally, it’s possible to add different resources to the single nodes when vertically scaling your applications.

Weighing It All Up

The reality is simple. Node.js has more advantages than disadvantages, and in terms of workflow it’s more efficient. What is notable about the disadvantages is that they all appear to be relatively fixable, when compared with other tools. Node.js uses JavaScript, which makes it a good system for back-end development given the intuitive learning curve. Finally, there are more businesses using Node.js, and that more than anything really makes it the complimentary system to use when obfuscating JavaScript.
