    Exclamation My Java program gets a strange error

    I get a strange error message in my program here is my code:
    package code;
    import java.awt.FlowLayout;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JButton;
    import javax.swing.JOptionPane;
    import javax.swing.JTextField;
    import java.awt.event.ActionListener;
    import java.awt.event.ActionEvent;
    import java.util.Random;
     
    public class GUI extends JFrame{
    	private static final long serialVersionUID = 1L;
    	private JLabel label1;
    	private JButton button1;
    	private JTextField textbox1;
    	private JTextField textbox2;
    	private JTextField textbox3;
     
    	Random Rn = new Random();
    	int number;
     
    	String p1;
    	String p2;
    	String p3;
     
    	for(int counter=0; counter<1; counter++){
    		number = Rn.nextInt(3);
    	}
     
    	public GUI(){
    		setLayout(new FlowLayout());
     
    		label1 = new JLabel("Enter names.");
    		add(label1);
     
    		textbox1 = new JTextField("Player 1");
    		add(textbox1);
     
    		textbox2 = new JTextField("Player 2");
    		add(textbox2);
     
    		textbox3 = new JTextField("Player 3");
    		add(textbox3);
     
    		button1 = new JButton("OK");
    		add(button1);
     
    		HandlerClass handler = new HandlerClass();
    		button1.addActionListener(handler);
    	}
    	private class HandlerClass implements ActionListener{
    		public void actionPerformed(ActionEvent event) {
    			switch (Rn.nextInt()){
    			case 1:
    				JOptionPane.showMessageDialog(null, p1 + "IS AWESOME!");
    				break;
    			case 2:
    				JOptionPane.showMessageDialog(null, p2 + "IS AWESOME!");
    				break;
    			case 3:
    				JOptionPane.showMessageDialog(null, p3 + "IS AWESOME!");
    				break;
    			}
    		}
     
    	}
    }

    an a error on line 29 saying: Syntax error, inset "}" to complete Block
    but if i remove
    for(int counter=0; counter<1; counter++){
    	      number = Rn.nextInt(3);
             }

    You can't have expressions like for loops outside a method.
