Question

上下文我正在尝试在Jcreator中创建一个视频播放器，但问题是它给出了以下错误

  --------------------Configuration: newPlayer - JDK version 1.7.0_55 <Default> - <Default>--------------------

    public class newPlayer {
        JFrame frame;
        Player play;

        JFileChooser chooser;
        public void Pla()
        {

            frame.setSize(1500,1500);
            frame.setLayout(new BorderLayout());
            chooser=new JFileChooser();

        } 

            Component view=play.getVisualComponent();
                //adds video component
            Component ctrl=play.getControlPanelComponent();
            frame.add(view,BorderLayout.CENTER);
            frame.add(ctrl,BorderLayout.SOUTH);
            frame.setVisible(true);
            play.start();

        }
        public static void main(String[]argo)
        {
            newPlayer f=new newPlayer();
