import java.util.Arrays;public class ArrayDemo{    public static void main(String[] args) {        int size = 4; // 数组大小        int[] myList = new int[size];// 定义数组        myList[0] = 5;        myList[1] = 12;        myList[2] = 33;        myList[3] = 52;        System.out.println(Arrays.toString(myList));    }}

 如果是多维数组使用

Arrays.deepToString(arr)
