要编一个猜数字的程序 猜10次没猜到就失败 怎么编
Java代码：
public class Game{
public static void main(String[] args){
Game g = new Game();
g.gameTest(3);-----------3的位置输入你想让别人猜得数字
}
public void gameTest(int num){
for(int count = 0 ; count 10 ; count++){
Scanner scan = new Scanner(System.in);
int in = scan.nextInt();
if(in == num){
System.out.println("恭喜答对了！");
break;
}
else if(count9){
System.out.println("对不起，答错了！您还有"+(9-count)+"次机会");
continue;
}
else if(count == 9){
System.out.print("游戏失败！");
break;
}
}
}
}

用JavaScript写猜数字游戏？
document.write("input type='text' id='inval' name='inval'/"); //数字框
document.write("input type='button' onclick='Guess();' value='提交'"); //按钮
function Guess() {
var inputVal=document.getElementById("inval").value; //获取文本框的值
var curRand=parseInt(100*Math.random()); //获取随机数
if(!isNum(inputVal))
{
alert("不是数字，请重新输入");
return;
}
if(inputVal){
if(inputValcurRand){
alert("胜利");
} else if (inputValcurRand){
alert("输了");
} else {
alert("平局");
}
}
}
//判断是否是数字，true表示是数字
function isNum(value) {
return !isNaN(value);
