Java AWT Toolkit Example

import java.awt.*;
public class ToolkitExample {
  public static void main(String[] args) {
	  Toolkit t = Toolkit.getDefaultToolkit();
	  System.out.println("Screen resolution = " + t.getScreenResolution());
	  Dimension d = t.getScreenSize();
	  System.out.println("Screen width = " + d.width);
	  System.out.println("Screen height = " + d.height);
  }
}

Output:

Screen resolution = 96
Screen width = 1366
Screen height = 768

import java.awt.event.*;
public class ToolkitExample {
public static void main(String[] args) {

	f.add(b);	
	f.setSize(300,300);
	f.setLayout(null);
	f.setVisible(true);
	b.addActionListener(new ActionListener(){
		public void actionPerformed(ActionEvent e){
			Toolkit.getDefaultToolkit().beep();
