标签: javascript java eclipse applet

当我运行我的代码时,我会在左下角看到一个小程序窗口,其中显示“Start:applet not initialized”。我实际上没有安装JRE,但得到了离线安装程序并指定它在“eclipse.ini”中的位置,这可能是个问题吗?下面是我的代码和我在applet和控制台中得到的错误。

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JButton;

import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class SpMain extends JFrame implements ActionListener{
    private static final long serialVersionUID = 1L;

    JButton define, conjugate, close;

    SpMain(String title){

        super(title);

        this.setSize(375, 190);
        this.init();
        this.setVisible(true);
    }

    private void init() {

        setAlwaysOnTop(true);

        JLabel lchoose = new JLabel("Define or Conjugate?");

        define = new JButton("Define");
        conjugate = new JButton("Conjugate");
        close = new JButton("Close");

        define.addActionListener(this);
        conjugate.addActionListener(this);
        close.addActionListener(this);

        JPanel panel = new JPanel();
        panel.add(lchoose);
        panel.add(define);
        panel.add(conjugate);
        panel.add(close);

        this.add(panel);
    }

    public void setDefaultCloseOperation(int exitOnClose) {}

    @Override
    public void actionPerformed(ActionEvent event) {

        if(event.getSource() == define){
        }

        else if(event.getSource() == conjugate){
        }

        else if(event.getSource() == close){
            System.exit(0);
        }
    }
}
