编写一个Java应用程序，在主线程中再创建一个Frame类型的窗口，在该窗口中再创建1个线程giveWord。线程giveWord每隔2秒钟给出一个汉字，用户使用一种汉字输入法将该汉字输入到文本框中。

WordThread.java

import java.awt.*;public class WordThread extends Thread{  	int  time = 6000;	char word;    int k=19968;    Label com;     WordThread(Label com)    {  this.com=com;    }        public void run()    {         k=19968;       while(true)        {          word=(char)k;          com.setText(""+word);          try{  //【代码1】//调用sleep方法使得线程中断6000豪秒        	  //sleep(6000);        	  //更改为线程中断time毫秒        	  sleep(time);             }          catch(InterruptedException e){}           k++;          if(k>=29968) k=19968;        }    }     public void setTime(int n) {    	time = n;    }}

ThreadFrame.java

import java.awt.*;import java.awt.event.*;public class ThreadFrame extends Frame implements ActionListener {	Label wordLabel;	Button button;	TextField inputText, scoreText;	WordThread giveWord;// 【代码2】// 用WordThread声明一个giveWord对象	int score = 0;	ThreadFrame() {		wordLabel = new Label(" ", Label.CENTER);		wordLabel.setFont(new Font("", Font.BOLD, 72));		button = new Button("开始");		inputText = new TextField(3);		scoreText = new TextField(5);		scoreText.setEditable(false);		// 【代码3】//创建giveWord，将wordLabel传递给WordThread构造方法的参数		giveWord = new WordThread(wordLabel);		button.addActionListener(this);		inputText.addActionListener(this);		add(button, BorderLayout.NORTH);		add(wordLabel, BorderLayout.CENTER);		Panel southP = new Panel();		southP.add(new Label("输入标签所显示的汉字后回车:"));		southP.add(inputText);		southP.add(scoreText);		add(southP, BorderLayout.SOUTH);		setBounds(100, 100, 350, 180);		setVisible(true);		validate();		addWindowListener(new WindowAdapter() {			public void windowClosing(WindowEvent e) {				System.exit(0);			}		});	}	public void actionPerformed(ActionEvent e)   {      if(e.getSource()==button)      {  if(!(giveWord.isAlive()))     //giveWord调用方法isAlive()         {       	  giveWord=new WordThread(wordLabel);         }         try         {    //【代码5】//giveWord调用方法start()        	 giveWord.start();         }         catch(Exception exe){}      }      else if(e.getSource()==inputText)      {  if(inputText.getText().equals(wordLabel.getText()))          {      	  score++;          }         scoreText.setText("得分:"+score);         inputText.setText(null);      }   }}

ThreadWordMainClass.java

public class ThreadWordMainClass{    public static void main(String args[])   { 	new ThreadFrame();   } }
