Well just so I get back into the groove of making tutorials, I am going to make a quick Hello World graphical user interface window. I'm not with my compiler right now and it has been a few weeks since I have worked on a GUI (currently working on an IRCd made in java with services written in tcl{i know lol}

Alright here we go.

import javax.swing.*; 

import java.awt.*; 

import java.awt.event.*; 

public class helloWorld extends JFrame {
    helloWorld(String title) { 
        this.setSize(500,500); 
        setTitle(title); 
    }

    public static void main(String[] args) {
       helloWorld window = new helloWorld("Hello CodeCall");
       window.setVisible(true);
       window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    }
}

Basically this opens a 500x500 window titled "Hello CodeCall"

Please remember I did this without my compiler(yes, I know this is simple, but also consider I havent done a GUI in a matter of weeks, if not months)

It uses AWT/Swing, so you may need to edit it a bit to get it to work. There are other password input tutorials on the web too if you search which are quite nice. Try not to create so many posts in one place!

okay . thank you

You dont need these imports:

import java.awt.*;
import java.awt.event.*;

The code can run on Swing by itself.

hello.. well, on the same topic.. u can build this hello world using IDE (i choose Netbeans)

how ? ok, simple..
1-just made new project
2- add JButton on the JPanel
3 - right click on JButton that we add before > choose "event" > "ActionPerformed"
4 - add this code above the TODO (as IDE will generate it default to made u code it faster)

String msg = "Hello dunia!";
    JOptionPane.showMessageDialog(null,msg);
    System.out.println(msg)

5 - now try execute by compiling it!

example :
