两个数组的内存图

 

int[] array = new int[3]; //动态初始值
        System.out.println(array); //地址值
        System.out.println(array[0]);
        System.out.println(array[1]);
        System.out.println(array[2]);
        //改变数组当中元素的内容
        array[1] = 50;
        array[2] = 60;
        System.out.println(array);  //地址值
        System.out.println(array[0]);   //0
        System.out.println(array[1]);   //50
        System.out.println(array[2]);   //60

        System.out.println(array[2]);   //60
        System.out.println("=====================");
        //将第一个数组的地址值赋给第二个数组
        int[] arrayB = array; //动态初始值
        System.out.println(arrayB); //地址值
        System.out.println(arrayB[0]);//0

        System.out.println(arrayB[2]);//60
        //改变数组当中元素的内容
        arrayB[1] = 80;
        arrayB[2] = 100;
        System.out.println(arrayB);  //地址值
