how to use jFrame in java code example

Example 1: java create jframe

import javax.swing.JFrame;

public class example {
  public static void main(String[] args){
    JFrame frame = new JFrame();
    frame.setSize(100,100);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOES);
    frame.setTitle("Example Frame");
    frame.setVisible(true);
  }
}

Example 2: how to create a JFrame in java

import javax.swing.JFrame;
import java.awt.Rectangle;
import javax.swing.JComponent;
import java.awt.Graphics2D;
import java.awt.Graphics;
import java.awt.Color;

public class ChrismasTree {
    public static void main(String[] args) {
        JFrame window = new JFrame();
        window.setTitle("Christmas Tree");
        window.setSize(800, 1000);
        window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        window.setVisible(true);
        DrawingComponent DC = new DrawingComponent();
        window.add(DC);
    }
}

class DrawingComponent extends JComponent{
    public void paint(Graphics graph0){
        Graphics2D graph = (Graphics2D) graph0;

        graph.setColor(Color.LIGHT_GRAY);
        graph.draw(new Rectangle(0, 710, 70, 60));

        graph.setColor(Color.BLUE);
        graph.draw(new Rectangle(70, 600, 50, 100));

        graph.setColor(Color.BLACK);
    }
}

Example 3: java create window

//THIS IS A FIX OF THE ONE BY FRANCY FROG
//THEY FIXED THEIRS
import javax.swing.JFrame;

public class example {
  public static void main(String[] args){
    JFrame frame = new JFrame();
    frame.setSize(100,100);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setTitle("Example Frame");
    frame.setVisible(true);
  }
}

Example 4: java simple jframe example

import javax.swing.*;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.*;
 
public class JFrameExample{
     
    public static void main(String[] args){
        // Create frame with title Registration Demo
        JFrame frame= new JFrame(); 
        frame.setTitle("JFrame Demo");
        frame.pack();
        frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}

Example 5: java making a screen

import java.awt.*;
import javax.swing.*;

public class Screen{
    
    private GraphicsDevice graphicsDevice;
    
    public static void main(String[] args){
        
        Screen screen = new Screen();
    }
    public Screen(){
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        JFrame jFrame = new JFrame();
        
        MakeDefaultScreen(jFrame,screenSize);
        
        System.out.println("Program Started");
    }
    public void MakeDefaultScreen (JFrame jFrame,Dimension screenSize){
        jFrame.setSize(screenSize.width,screenSize.height);
        jFrame.setVisible(true);
        jFrame.setResizable(true);
    }
}

Example 6: how to create a java jframe
