用JAVA编写一个小游戏
前天写的猜数字游戏，yongi控制猜测次数，有详细解析，用黑窗口可以直接运行，
我试验过了，没问题
import javax.swing.Icon;
import javax.swing.JOptionPane;
public class CaiShuZi4JOptionPane{
/**
*@param args
*/
public static void main(String[] args){
Icon icon= null;
boolean bl= false;
int put= 0;
int c=(int)(((Math.random())*100)+1);//获取一个1-100的随机数
System.out.println("你获取的随机数是："+c);//打印你的随机数字
String str1=(String) JOptionPane.showInputDialog(null,"请输入你的猜测数字(1-100)：\n","猜数字游戏",JOptionPane.PLAIN_MESSAGE,icon,null,"在这输入");//第一次输入你的猜测数字
if(str1==null){
JOptionPane.showMessageDialog(null,"你已经取消了本次游戏");//如果你点取消那么本次游戏结束
}else{
bl= num(str1);//判断是输入的是不是数字或者是整数
if(true==bl){//如果是数字的话进入与随机数比较的程序
System.out.println("你输入的数字是："+str1);//打印你输入的数字
put= Integer.valueOf(str1);
for(int i= 4;i> 0;i--){//i是你可以猜测的次数
if(put==c){
JOptionPane.showMessageDialog(null,"恭喜你猜对了，正确答案是:"+c+"。");//如果你猜对了就直接结束循环
break;
}else if(put>c){//如果输大了就让你再次从新输入
str1=(String) JOptionPane.showInputDialog(null,"你的输入过大。你还有"+i+"次机会，请重新输入：\n","猜数字游戏",JOptionPane.PLAIN_MESSAGE,icon,null,"在这输入");
if(str1==null){

break;
}else{
