Read any key to continue Java

Question

How can I implement the press ANY key to continue in Java. In C I use getch() and it works fine but Java I must press enter in every read method implement in every OutputStream class.

Thanks in advance.

I found a code, Equivalent function to C's “_getch()

I have given answer for this question Equivalent function to C's "_getch()" in Java? see my answer here

or use the code

public static void getCh() {

        final JFrame frame = new JFrame();

        synchronized (frame) {

            frame.setUndecorated(true);

            frame.getRootPane().setWindowDecorationStyle(JRootPane.FRAME);

            frame.addKeyListener(new KeyListener() {

                public void keyPressed(KeyEvent e) {

                    synchronized (frame) {

                        frame.setVisible(false);

                        frame.dispose();

                        frame.notify();

                    }

                }  

            public void keyReleased(KeyEvent e) {  
            }  

            public void keyTyped(KeyEvent e) {  
            }  
        });  
        frame.setVisible(true);  
        try {  
            frame.wait();  
        } catch (InterruptedException e1) {  
        }  
    }  
}

You can use following code if you're using windows.

new ProcessBuilder("cmd", "/c", "pause").inheritIO().start().waitFor();

and import following package.

import java.io.IOException;

and change main function to this.

public static void main(String args[]) throws IOException, InterruptedException
