用JAVA语言编写一个“猜数字游戏”的程序
int num = (int)(Math.random()*100)+1;
Scanner sc = new Scanner(System.in);
int guessNum = -1;
while (guessNum != num) {
System.out.println("请输入1-100之间整数");
guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNum num) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
}
扩展资料：
编写思路
1、成1-100之间随机数
(int)(Math.random()*100)+1;
提示用户输入数字，
Scanner sc=new Scanner(System.in);
int guessNum = sc.nextInt();
需要将随机数和用户输入的数字进行比较。
猜一次：
Scanner sc = new Scanner(System.in);
int num = (int)(Math.random()*100)+1;
System.out.println("请输入0-100之间整数");
int guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNum num) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
二、使用while循环
publicstaticvoid main(String[] args) {
int num = (int)(Math.random()*100)+1;
Scanner sc = new Scanner(System.in);
while (true) {
System.out.println("请输入1-100之间整数");
int guessNum = sc.nextInt();
if (guessNum == num) {
System.out.println("中啦");
} elseif (guessNum num) {
System.out.println("小啦");
} else {
System.out.println("大了");
}
}
}
三、最后用while() 括号中的条件表达式，当用户猜测的数和系统生成的数字不相等时，就需要继续循环。

如何用Java语言实现猜数字游戏
java实现的简单猜数字游戏代码,通过随机数与逻辑判断来实现游戏功能 代码如下： import java.util.InputMismatchException; import java.util.Scanner; public class Main { public static void main(String[] args) { // 产生一个随机数 int n
