How to clear previous menu in command prompt

[Xdawn90]

Hi,

I have a main menu with 3 options - 1, 2, and 3. When i enter 1 another menu will appear and the main menu will disappear. The menu will not stack one after another. How can I do that ? Can someone teach me how to do it ?

Help is very much appreciated.

Thanks.

Do you mean you're using command lines as menu or Java swing?

Ya I am using command line. Is it possible to do that ? If yes please teach me how to do it.

Test class

import java.awt.*;
import java.awt.event.*;
 
public class Test extends Frame implements WindowListener {
	private static final long serialVersionUID = 1L;
	private final TextArea TA = new TextArea
            ("", 25, 80, TextArea.SCROLLBARS_NONE);
    private final String NEWLINE = "" + '\n';
    
    public Test() {
        TA.setEditable(false);
        add(TA);
        setTitle("Test Application");
        setResizable(false);
        addWindowListener(this);
        pack();
        setVisible(true);
    }
    public void print(String s) {
        TA.append(s);
    }
    public void println(String s) {
        TA.append(s);
        TA.append(NEWLINE);
    }
    public void cls() {
        TA.setText("");

Clearscreen

public class clearscreen {
	 
	public static void main(String[] args) {
	        Test t = new Test();
	        t.println("Hello World!");
	        t.print("Same line ");
	        t.println("Test");
	        try {
	            Thread.sleep(5000);
	        } catch (InterruptedException e) 
	        }
	        t.cls();
	        try {
	            Thread.sleep(5000);
	        } catch (InterruptedException e) {
	        }
	        t.kill();        
	    }
	}

Try this...

hmm ... I have try the code but this is not what i wanted it to be. Anyway, thanks very much for your kind help.

I wanted to know how to create a menu (not in GUI) in a command prompt using java. For example, i have 4 options for my menu - a,b,c,d and when the user enter b and press enter, the main menu will disappear and menu b will appear. Is it possible to do that ?

Sorry for my unclear description.

Thanks.

I think the commands "cls" clears the screen

Yes indeed it does in c++
However in java I have never seen with an IDE or whatever so command cls
Am I stupid?

He posted it in the java board but I think he misplaced it - he said "command prompt" which is the windows "command line" right? I was under the impression he just put this in the wrong place.
