数组的内存图

一个数组的内存图

        int[] arr = new int[3];
        System.out.println(arr);
        System.out.println(arr[0]);
        System.out.println(arr[1]);
        System.out.println(arr[2]);
        System.out.println("==========");
        arr[1]=10;
        arr[2]=20;
        System.out.println(arr);
        System.out.println(arr[0]);
        System.out.println(arr[1]);
        System.out.println(arr[2]);
