java - 编译程序时出现错误 'void' type not allowed here

Question

我正在尝试创建一个程序，要求 10 个整数并将这些数字放入负数、正数和奇数数组的数组中。最后，我希望程序打印出 3 行数字，将用户 10 个数字分为“奇数”、“偶数”和负数。当我运行此程序时，我收到“错误:此处不允许'void'类型” ”

import java.util.Scanner;

public class ArrayPractice{

   private static void showArray(int[] nums)
   {
      for (int i=0; i<nums.length;i++)
      {
         if(nums[i]!=0)
         {
            System.out.println(nums[i] + " ");
         }
      }
   }

   public static void main(String[] args){
      int evenArray[] = new int[10];
      int evenCount = 0;
      int oddArray[] = new int[10];
      int oddCount = 0;
      int negArray[] = new int[10];
      int negCount = 0;
      Scanner input = new Scanner(System.in);
      for(int i = 0; i<10; i++)
      {
         System.out.println("Number? " + (i + 1));
         int answer = input.nextInt();
         if(answer<0)
         {
            negArray[negCount++] = answer;
         }
         else
         {
            if (answer % 2 == 0)
            {
               evenArray[evenCount++] = answer;
            }
            else
            {
               oddArray[oddCount++] = answer;
            }
         }
      }
      System.out.println(showArray(evenArray));       
      System.out.println(showArray(oddArray));
      System.out.println(showArray(negArray));

   }
}

Answer 1

showArray 是 void，它不返回任何内容。并且，经过检查，它会在方法本身中打印。所以这个

System.out.println(showArray(evenArray));       
System.out.println(showArray(oddArray));
System.out.println(showArray(negArray));

应该是

showArray(evenArray);       
showArray(oddArray);
showArray(negArray);
