我该如何设置限制 [英] How can I set a limit

问题描述

我用Java编写了一个练习程序，计算机会在其内存中保存一个随机数，用户必须猜测它。每次用户猜错号码时，编译器要求再次尝试，但我想设置一个限制到该程序，如果用户猜测数字8次，则程序停止。任何帮助将不胜感激。



我尝试过：

I have made a practice program in Java in which computer will save a random number in it's memory and the user has to guess it. Everytime user guesses a wrong number, The compiler asks to try again,But i want to set a limit into that program that if the user guesses the number 8 times,then the program stops. Any help would be appreciated.

What I have tried:

public static void main(String[] args) {
		Random nums = new Random();
		int ran= nums.nextInt(100);
		
		System.out.printf("Please enter a value: %n");
		
		Scanner scan = new Scanner(System.in);
		
		int Value1;
		do {
			
			
			 Value1= scan.nextInt();
			
			if(Value1 > ran) {
			System.out.println("You entered "+ Value1 + " which is greater than guess Please try again:");
			
		}else if (Value1 < ran){
			System.out.println("You entered "+ Value1 + " which is lesser than guess Please try again:");
		}else {
			System.out.println("Good job");
		}
			/*int tries= 8;
			for(int i=0; i ==tries;i++) {
			if(Value1==i) {
			System.out.println("Game Over");
			
			}
			}*/
			
		}while(Value1!=ran);
		scan.close();
		
	}

推荐答案

这里是我的建议。包含一个变量来跟踪尝试次数。如果猜数> 8，显示消息，退出循环。如果用户猜出正确的数字，请立即退出循环。这是一个例子： https://www.jdoodle.com/embed/v0/zQq



注意：要测试它，请打开交互模式，然后单击执行按钮。

Here my suggestion. Include a variable to track number of attempt. If the number of guess > 8, display a message, exit the loop. If the user guess the correct number, exit the loop immediately. here is an example: https://www.jdoodle.com/embed/v0/zQq
