    Default GUI HELP

    I've just started to learn GUI and I'm trying to learn how to make the window open full screen, could someone please add it in cause GUI makes no sense to me.

    import javax.swing.*;
    import java.awt.Component;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
     
    public class HelloWorld implements ActionListener{
    	static String text= "hello world";
    	public static int count1;
    	public static int count2;
    	JFrame frame;
    	JPanel content;
    	JLabel lblGeneral1;
    	JLabel lblGeneral2;
    	JButton btnTest1;
    	JButton btnTest2;
    	JLabel label1;
    	JLabel label2;
     
    	public HelloWorld(){
    		//create frame
    		frame=new JFrame ("Hello World");	
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);	
     
    		//create panel
    		content= new JPanel();
    		content.setLayout(new BoxLayout(content, BoxLayout.PAGE_AXIS));
     
    		//set button1
    		btnTest1=new JButton("Superior");
    		btnTest1.setActionCommand("1");
    		btnTest1.addActionListener(this);
    		btnTest1.setAlignmentY(Component.CENTER_ALIGNMENT);
    		btnTest1.setAlignmentX(Component.LEFT_ALIGNMENT);
    		content.add(btnTest1);
     
    		//set button2
    		btnTest2=new JButton("Superior");
    		btnTest2.setActionCommand("2");
    		btnTest2.addActionListener(this);
    		btnTest2.setAlignmentY(Component.CENTER_ALIGNMENT);
    		btnTest2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    		content.add(btnTest2);
     
    		//create label
    		lblGeneral1=new JLabel(Integer.toString(count1));
    		lblGeneral1.setAlignmentY(Component.BOTTOM_ALIGNMENT);
    		lblGeneral1.setAlignmentX(Component.LEFT_ALIGNMENT);
    		content.add(lblGeneral1);
     
    		//create label
    		lblGeneral2=new JLabel(Integer.toString(count2));
    		lblGeneral2.setAlignmentY(Component.BOTTOM_ALIGNMENT);
    		lblGeneral2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    		content.add(lblGeneral2);
     
    		//add picture box
    		String imgStr = "Penguins.jpg";		
    		ImageIcon image = new ImageIcon(imgStr);
    		JLabel label1 = new JLabel(image);
    		label1.setAlignmentY(Component.TOP_ALIGNMENT);
    		label1.setAlignmentX(Component.LEFT_ALIGNMENT);
    		content.add(label1);
     
    		//add picture box
    		String imgStr2 = "Penguins.jpg";		
    		ImageIcon image2 = new ImageIcon(imgStr);
    		JLabel label2 = new JLabel(image);
    		label2.setAlignmentY(Component.TOP_ALIGNMENT);
    		label2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    		content.add(label1);
     
    		//content to frame
    		frame.setContentPane(content);
     
    		//set display
    		frame.pack();
    		frame.setVisible(true);
    	}
     
    	//handle button click
    	public void actionPerformed(ActionEvent event){
    		String btn=event.getActionCommand();
    		if (btn.equals("1"))
    			count1++;
    		else
    			count2++;
    		lblGeneral1.setText(Integer.toString(count1));
    		lblGeneral2.setText(Integer.toString(count2));
     
    	}
     
    	//show the GUI
    	public static void runGUI(){
    		JFrame.setDefaultLookAndFeelDecorated(true);
    		HelloWorld greeting=new HelloWorld();
    	}
     
    	public static void main (String[] args){
    		//methods that show GUI should be run from a event dispatcher
    		count1=0;
    		count2=0;
    		javax.swing.SwingUtilities.invokeLater(new Runnable(){
    			public void run(){
    				runGUI();
    			}
    		});
    	}	
    }

    We are not a code service, but we will help you should you have problems in your attempts. Yet I fail to see what you've attempted. Did you search the internet or look through the API to look for a solution? With what you found, what did you try and what happened?
    And please wrap your code in the proper tags([highlight=java][/highlight])

    Default Re: GUI HELP

    I searched up how to make a GUI jframe open in a maximized window setting, but i'm new to programming and didn't really understand what the suggestions were. I tried some method called setExtendedState(MAXIMIZED_BOTH), but the different ways I integrated it either crashed the program or had no effect. I'm just trying to find out the command I should use and how to properly integrate it.

    (p.s. this was my first ever post on a programming forum, sorry for forgetting proper etiquette)
