13.9.1 实验一 键盘操作练习

实验目的：

     掌握使用Thread的子类创建线程的方法

Main.java

public class Main {
    public static void main(String[] args) {
        System.out.println("键盘练习（输入#结束程序）");
        System.out.printf("输入显示的字母（回车）\n");
        Letter letter;
        letter=new Letter();
        GiveLetterThread giveChar;
        InputLetterThread typeChar;
        giveChar=new GiveLetterThread();
        giveChar.setLetter(letter);
        giveChar.setSleepLength(3200);
        typeChar=new InputLetterThread();
        typeChar.setLetter(letter);
        giveChar.start();
        typeChar.start();
    }
}

Letter.java

public class Letter {
char c='\0';
public  void setChar(char c){
    this.c=c;
}
public char getChar(){
    return c;
}
}

InputLetterThread.java

import java.awt.*;
import java.util.Scanner;
public class InputLetterThread extends Thread{
