Write a JAVA application that generates a random number between 1 and 20 inclusive and requires the user to guess the random number generated. If the user’s input matches the random number, an output message should appear indicating that the user guessed correctly.Otherwise the user should be informed whether their guess is too high or too low and prompted for another guess. The user can have a total of 3 guesses before the game is over and the computer wins.(这是原文)
写一个JAVA的程序， 它可以自己从1到20中选出一个数字 然后user有3次机会猜。 每次输入时 电脑会告诉你高了还是低了。 猜了3次后 还没答对 会显示电脑赢 游戏结束。
如果user输入了20以上的数 会出现错误提示 必须20以内

import java.util.Random;

import javax.swing.JOptionPane;
public class Guess {
int []a=new int[3];//存放随机数
int count=0;//猜对次数
Random r=new Random();
Guess(){
MyThread mt=new MyThread();
mt.start();//启动线程
for(int i=0;i<a.length;i++){
String input=JOptionPane.showInputDialog("请输入一个正整数：");
if("".equals(input)||input==null){
continue;
}
int m=Integer.parseInt(input);
if(m==a[i]){
JOptionPane.showMessageDialog(null, "回答正确");
count++;
}else if(m>a[i]){
JOptionPane.showMessageDialog(null, "大了");
}else {
JOptionPane.showMessageDialog(null, "小了");
}
}
if(count==0){
JOptionPane.showMessageDialog(null, "你输了，游戏结束");
}else{
JOptionPane.showMessageDialog(null, "你猜对了"+count+"次");
}
}
