Question

我有一个我为编程编写的Java代码，但是当我们只允许使用while循环时，我使用了for循环。我怎样才能将其转换为while循环？

代码的意图是获取用逗号分隔的输入数字，并告诉它有多少连续的重复数字。即1,1是连续的，但2,1,2不是。

import java.util.Scanner;

public class ConsecDouplicates {

  public static void main(String[] args) {

Scanner scan = new Scanner(System.in);


System.out.print("Enter numbers: ");
String str = scan.nextLine();


String[] numbers = str.split(",");

Integer last = null;
Integer current = null;
int total = 0;

for (String number: numbers) {

  current = Integer.parseInt(number);


  if (last != null) {
    if(last == current){
      System.out.println("Duplicates: " + current);
      total = total +1;
    }
  }
  last = current;

}
System.out.println("Total duplicates: " + total);
  }
}

我认为你的其他逻辑很好，那么你可以简单地将for转换为while循环，如下所述：

    int count = 0;

    while ( count < numbers.length) {

      current = Integer.parseInt(numbers[count]);


      if (last != null) {
        if(last == current){
          System.out.println("Duplicates: " + current);
          total = total +1;
        }
      }
      last = current;
      count++;

    }
