java - 用于计算 java 运行次数的计数器

Question

这是我的代码，它接受一个输入值并将其与一个随机值进行比较我有 15 次运行代码来估计并获得等于代码决定的随机值的输入值......我想做一个计数器来计算我运行代码的次数......我试着把 count++;在代码的不同地方，但我没有得到正确的答案......你认为在哪里算++;应该放在输出中以获得运行次数......谢谢

这是我的代码

package person;

import java.util.Random;
import java.util.Scanner;

public class Cat {

    public static void main(String[] args) {

        int max = 100;
        int min = 0;
        int diff = max-min;
        Random rn = new Random();
        int i = rn.nextInt(diff+1);
        i+=min;
        for (int k=0; k<15; k++){
          int count=0;
          Scanner sb = new Scanner(System.in);
          System.out.println("Enter your number");
          int x = sb.nextInt();
          if(x>i){
            System.out.println(x+"is bigger than i");
          } else if(x<i){
            System.out.println(x+"is smaller than i");
          } else if (x==i){
            System.out.println(x+"is equals to i "+" "+" no. of try"+count);
            break;
          }
        }
    }
}

您的方法的问题在于您的计数处于循环中，因此它总是会被重置。您可以将其移出循环或仅打印计数器循环变量。

package person;

import java.util.Random;
import java.util.Scanner;

public class Cat {

    public static void main(String[] args) {

        int max = 100;
        int min = 0;
        int diff = max-min;
        Random rn = new Random();
        int i = rn.nextInt(diff+1);
        i+=min;
        int k;
        for (k=0; k<15; k++) {
            Scanner sb = new Scanner(System.in);
            System.out.println("Enter your number");
            int x = sb.nextInt();
            if(x>i) {
                System.out.println(x+"is bigger than i");
            } else if(x<i) {
                System.out.println(x+"is smaller than i");
            } else if (x==i) {
                System.out.println(x+"is equals to i "+" "+" no. of try"+k+1);
                break;    
            }
        }
        if(sb !=null) {
            sb.close();
        }
    }
}
