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。

用java编写一个猜字游戏程序，答案不限
import java.util.Scanner;
public class Test {
public static void main(String[] args) {

猜数字游戏0-1000之间，用JAVA编程
这简单，代码如下,这是我用记事本写的，没运行过可能有点问题，你修改下就可以了，创建个类以Number 命名，然后直接复制粘贴就可以了。希望能帮到你！import java.util.Scanner;public class number { public static void main(String[] args) {do{
int i = 0; int random = (int) (Math.random() * 1000);
System.out.println("我心里有一个0到1000之间的整数，你猜是什么？");
for (i = 0; i 20; i++) {
Scanner input = new Scanner(System.in);
int f = input.nextInt();
if(frandom){
System.out.println("大了点，再猜！");
} else if (f random ){
System.out.println("小了点，再试试！");
} else if (f == random i == 1){
System.out.println("猜对了！\n"+"你太有才了！");
} else if (f == random i = 2 i = 6) {
System.out.println("猜对了！\n"+"这么快就猜出来了，很聪明！");
} else if (f == random i = 7){
System.out.println("猜对了！\n"+"猜了半天才猜出来，老大，你尚需努力啊！"); System.out.println("你要继续吗？（yes / no）"); answer=input.next();}
} while(answer.equals("yes")); } }}
