我做课程设计的最初代码参考下吧运行时先看帮助~
java如何实现的简单猜数字游戏代码主要通过随机数与逻辑判断来实现游戏功能
实现代码如下java猜数字窗体代码：
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 number = (int) (Math.random() * 100)1;
// 加入count
int count = 0;
// 在这里加入最大值java猜数字窗体代码，和最小值
int max = 100;
int min = 1;
while (true) {
// 键盘录入数据
Scanner sc = new Scanner(System.in);
System.out.println("请输入java猜数字窗体代码你要猜的数据：("min"~"max")");
try {
count;
int guessNumber = sc.nextInt();
// 判断
if (guessNumbernumber) {
max = guessNumber;
System.out.println("你猜大java猜数字窗体代码了");
} else if (guessNumbernumber) {
min = guessNumber;
System.out.println("你猜小了");
} else {
System.out.println("恭喜你,花了"count"次就猜中了");
// 问是否继续
System.out.println("请问还要继续吗？(yes)");
sc = new Scanner(System.in);
String str = sc.nextLine();
if ("yes".equals(str)) {
// 重写赋值随机数
number = (int) (Math.random() * 100)1;
count = 0;
max = 100;
min = 1;
} else {
break;
}
}
} catch (InputMismatchException e) {
System.out.println("你输入的数据有误");
}
}
}
java编写一个“猜数”程序:该程序随机在1到1000的范围中选择一个供用户猜测的整数Java源程序附后 。
本程序的特点是：
(1) 文本框只能输入纯数字；
(2) 界面较美观；
(3) 代码可读性较好，有适当的注释；
(4) 窗体一出现就在桌面居中 。
