打印数组（不用方法写）-526互联

public class HelloWorld {
    public static void main(String[] args) {
        //打印数组 [11,22,33]
        int[] arr = new int[]{11, 22, 33};    
        //  arr = [0,0,0]

        int[] arr2 = new int[arr.length];    //打印数组arr2
        for (int i = 0; i < arr.length; i++) {
            arr2 = arr;
            //arr2 = [0,0,0]
        }
        System.out.print("[");
        for (int i = 0; i < arr2.length; i++) {
            System.out.print(i ==arr.length-1 ?arr[i]:arr2[i] +",");
        }
        System.out.print("]");

    }
