怎么在Java中利用GUI制作一个单词答题游戏

public class Swing_exercise2 extends JFrame { //继承JFrame顶层框架

 //定义面板
 JPanel jp1;
 JPanel jp2;
 JPanel jp3;

 //定义拆分窗格
 JSplitPane jsp;
 JSplitPane jsp1;

 //定义文本域
 JTextArea jta1;
 TextField jta2;
 JTextArea jta3;

 //定义滚动窗格
 JScrollPane jspane1;
 JScrollPane jspane2;
 JScrollPane jspane3;


 //定义按钮
 JButton jb2;
 JButton jb3;
 JButton jb1;

 //定义显示区域
 JLabel jla1;

 //定义随机函数
 Random ran;
 private int sw; //屏幕宽度和高度
 private int sh; //屏幕宽度和高度
 private String ch;//随机单词
 private int Fen;//记录分数
 private int z;//记录正确题数
 private int x;//记录错误题数
 private int sun;//记录总题数

 public static void main(String[] args) {
 Swing_exercise2 a = new Swing_exercise2(); //显示界面

 //字体初始化 Times new roman：罗马字样 加粗

 Font font2 = new Font("Times new roman", Font.BOLD, 30);
 Font font1 = new Font("宋体", Font.BOLD, 20);
 Font font4 = new Font("宋体", Font.BOLD, 70);


 //创建随机函数
 ran = new Random();

 //创建面板
 jp1 = new JPanel();
 jp2 = new JPanel();
 jp3 = new JPanel();

 //创建多行文本框
 jta1 = new JTextArea();
 jta3 = new JTextArea();

 //创建单行文本框
 jta2 = new TextField(10);

 //设置多行文本框自动换行
 jta1.setLineWrap(true);
 jta3.setLineWrap(true);


 //创建滚动窗格
 jspane1 = new JScrollPane(jta1);
 jspane2 = new JScrollPane(jta2);
 jspane3 = new JScrollPane(jta3);

 //设置字体样式
 jta3.setFont(font1);
 jta2.setFont(font2);
 jta1.setFont(font);


 //创建拆分窗格
 jsp = new JSplitPane(JSplitPane.VERTICAL_SPLIT, jspane1, jspane2);
 jsp1 = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, jspane3, jsp);

 //分频器布局
 jsp.setDividerLocation(700); //设置拆分窗格分频器初始位置
 jsp.setDividerSize(10);  //设置分频器大小
 jsp1.setDividerLocation(0.5); //设置拆分窗格分频器初始位置
 jsp1.setDividerSize(10);  //设置分频器大小

 //设置调整单词显示区
 jla1 = new JLabel();
 jla1.setFont(font);

 //初始化显示页面
 ch = RandomWords();
 jla1.setText(ch);
 jla1.setSize(sw, sh);
 jla1.setSize(500, 500);
 jla1.setLocation(ran.nextInt(300), ran.nextInt(200));

 //设置颜色
 jla1.setForeground(Color.green);
 jla1.setBackground(Color.decode("#000cc"));


 //创建按钮
 jb2 = new JButton("确定");
 jb3 = new JButton("退出");
 jb1 = new JButton("重置");


 //设置布局管理
 jp1.setLayout(new BorderLayout()); //设置面板布局
 jp2.setLayout(new FlowLayout(FlowLayout.CENTER));
 jp3.setLayout(new BorderLayout());


 //添加组件
 jp1.add(jsp);
 jp2.add(jb2);
 jp2.add(jb1);
 jp2.add(jb3);
 jp3.add(jsp1);
 jta1.add(jla1);

 //初始化得分数据
 Fen=0;
 z=0;
 x=0;
 sun=0;


 //布置整体面板布局
 this.add(jp1, BorderLayout.CENTER);
 this.add(jp2, BorderLayout.SOUTH);
 this.add(jp3, BorderLayout.WEST);


 //设置窗体属性
 this.setTitle("单词游戏");     //设置界面标题
 this.setExtendedState(MAXIMIZED_BOTH);   //窗口最大化
 this.setLocation(1000, 200);    //设置界面初始位置
 this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //设置虚拟机和界面一同关闭
 this.setVisible(true);     //设置界面可视化

 //空格加鼠标确定事件监听
