    Post Whats wrong with my code?

    import javax.swing.*;
     
    public class AnimateJInternalFrame {
     
        JFrame jf=new JFrame();
        JInternalFrame jif=new JInternalFrame();
        Timer t;
     
        public AnimateJInternalFrame() {
     
            jf.setSize(700,700);
            jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            jf.setLayout(null);
     
     
            jif.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            jif.setLayout(null);
            jif.setBounds(50,50,300,300);
     
     
            jf.setVisible(true);
            jf.add(jif);
     
            t=new Timer(30,null);
            t.start();
            for(int i=50;i<500;i++){
                jif.setBounds(50,i,300,300);
                jif.setVisible(true);
                }
     
        }
        public static void main(String[] args) {
            new AnimateJInternalFrame();
     
        }
     
    }

    but it is'nt working.
    Can you explain what the code does and what you want it to do differently?

    to animate smoothly
    Use a Timer to change a component's position at specific times and display it at the new position before moving it to a new position.
