java - 如何创建一个计数器来计算输入最高薪水的人数？

Question

import java.util.Scanner;

public class Lab4a{
  public static void main(String[] args){
  Scanner keyboard = new Scanner(System.in);
  int numemployees, max, freq;

  System.out.print("Enter number of employees: ");
  numemployees = keyboard.nextInt();

  System.out.println("Enter salary for " + numemployees + " employees:");
  int[] salaries = new int [numemployees];

  max = salaries[0];
  for (int i=0; i < salaries.length; i++){
    salaries[i] = keyboard.nextInt();
    if (salaries[i] > max)
      max = salaries[i];
  }

  System.out.println("Maximum salary is " + max);
  System.out.println(" employees received " + max);
}

所以这个的输出是

输入员 worker 数:3输入 3 名员工的工资:100001500015000最高工资15000 员工领取15000

我想说的是，“2 名员工收到了 15000”。这就是我需要做的。请帮助我如何使用另一个循环建立该计数器......尽可能简单!谢谢!

像这样修改你的循环:

max = salaries[0];
freq = 1;
for (int i=0; i < salaries.length; i++){
  salaries[i] = keyboard.nextInt();
  if (salaries[i] > max) {
    freq = 1;
    max = salaries[i];
  } else if (salaries[i] == max) {
    ++freq;
  }
}
System.out.println(freq + " employees received " + max);
