How do I get constructors of a class object?

Below is an example that showing you how to get constructors of a class object. In the code below we get the constructors by calling the Class.getDeclaredConstructors() or the Class.getConstructor(Class[]) method.

package org.kodejava.example.reflect;

import java.lang.reflect.Constructor;

public class GetConstructors {
    public static void main(String[] args) {
        Class clazz = String.class;

        // Get all declared constructors and iterate the constructors to get their
        // name and parameter types.
        Constructor[] constructors = clazz.getDeclaredConstructors();
        for (Constructor constructor : constructors) {
            String name = constructor.getName();
            System.out.println("Constructor name= " + name);

            Class[] paramterTypes = constructor.getParameterTypes();
            for (Class c : paramterTypes) {
                System.out.println("Param type name = " + c.getName());

        // Getting a specific constructor of the java.lang.String
        try {
            Constructor constructor = String.class.getConstructor(new Class[] {String.class});
            System.out.println("Constructor     = " + constructor.getName());
        } catch (NoSuchMethodException e) {
