你程序里 for循环之外 已经输入了一次,所以for循环改成: for (int i = 1; i < 5;i++) 就行,
我修改了下你的代码:
import java.util.Random;
import java.util.Scanner;
public class test9 {
public static void main(String[] args) {
// 2、猜数游戏(产生1-100的随机数,5次没有猜中就退出,猜错了给予提示)
System.out.println("请输入你猜的数字:");
Scanner sc = new Scanner(System.in);
Random rand = new Random();
int n = rand.nextInt(101);
System.out.println(n);
int c = 0;
while (sc.hasNextInt()) {
if (sc.nextInt() == n) {
System.out.println("恭喜你猜对了!");
break;
} else {
c++;
System.out.println("不好意思你猜错了...");
if(c == 5){
System.out.println("Game Over");
break;
}
}
}
sc.close();
}
}

while循环条件改成i<5就成了,当i<=5的时候就会循环5次,再加上你前面还有一次输入,所以输错的情况下6次才会退出。
追问
但是第五次输入时就没提示了
追答
第五次的时候for循环结束,但是for循环内部还有一句输入语句,所以还能接收一次输入,但是不能进行判断输错还是输对。

for (int i = 1; i <=5;i++)
你把=去掉
成for (int i = 1; i <5;i++)就可以了
你前面已经输入了一次 又循环了5次 所以可以6次
