101.数组的内存图解2二个数组

    public static void main(String[] args) {
        int[] arr1 = new int[3];                //创建数组,长度为3
        int[] arr2 = new int[3];                //创建数组,长度为3
        System.out.println(arr1);                //打印数组的地址值
        System.out.println(arr2);
        arr1[0] = 10;                            //给第一个数组中第一个元素赋值
        arr2[1] = 20;                            //给第二个数组中第二个元素赋值
        System.out.println(arr1[0]);
        System.out.println(arr1[1]);
        System.out.println(arr1[2]);
        System.out.println("--------------------------------------");
        System.out.println(arr2[0]);
        System.out.println(arr2[1]);
        System.out.println(arr2[2]);
    }
