    Default java game errors

    I am receiving two errors that I'm not sure how to fix. The first is illegal start of expression at line "public void actionPerformed(ActionEvent e)" and no suitable method found for intersect JButton at line "if(blocker01.getBounds().intersects(r_wall))" . Any help would be appreciated.

     
    import java.awt.*;
    import javax.swing.*;
    import java.awt.event.*;
     
    public class gamePanel01 extends JPanel implements KeyListener
    {
        character ch1 = new character("Hero");
        int w,l;
     
        JButton blocker01;
        JButton blocker02;
        JButton blocker03;
        JButton blocker04;

        Image gamePanelBG = new ImageIcon(cl.getResource("images/gamePanel01.jpg")).getImage();
        ImageIcon PSUBlocker = new ImageIcon(cl.getResource("images/PSU_Helmet_Blocker.gif"));
        ImageIcon PSULionRight = new ImageIcon(cl.getResource("images/NittanyLion_Mini_Right.png"));
        ImageIcon PSULionLeft = new ImageIcon(cl.getResource("images/NittanyLion_Mini_Left.png"));
     
        public gamePanel01()
        {
        super();
        setLayout(null);
     
        add(ch1);    
        ch1.setIcon(PSULionRight);

    Default Re: java game errors

    By convention in Java, class names begin with capital letters.

    I believe your open and close curly braces do not match up. You have methods inside other methods which is not allowed in Java.
