为什么我得到Java的垃圾值时，打印数组？

问题描述

How do I even print arrays? I'm trying to experiment on some methods and all I keep on getting are garbage values. I tried to import the Arrays library - still didn't work.

    int []x = {1, 2, 3, 4, 5};
    int []y;
    y = x.clone();
    System.out.println(x);
    System.out.println(y);

解决方案

It is not a garbage value; it is the toString() implementation of int[],

If you want to print the contents of array

public void printArray(int[] arrray){
 for(int number: array){
   System.out.println(number);
 }
}
