1. I noticed you say “Get the location of our mouse x and y coordinate from the PointerInfo location object.” And I am no expert coder, but I am curious (and am taking a computer science class in high school where we learn Java) but is the PointerInfo object even used? You use the Point class in instantiate a MouseInfo object.

   • Also, this code was EXTREMELY helpful, I will be sure to support you when I have the time!

   • Hi Vladimir,

     I cleared up the comment in the code that might confuse you. The PointerInfo object is still called in this process. When we call MouseInfo.getPointerInfo() we actually get an instance of PointerInfo defined in the MouseInfo object. An then we call the getLocation() of this object which return an object of type Point.

2. That makes sense, getLocation() is a PointerInfo method. I kind of guessed that an instance of PointerInfo was created somewhere, but I wasn’t too sure.

   • Hello Vladimir,

     You can always take a look at the source code available in the JDK distribution, the source is included. Take a peek at the java.awt.MouseInfo class, you will see how the java.awt.PointerInfo class is created.
