How are arrays implemented in java?

Question

Arrays are implemented as objects in java right? If so, where could I look at the source code for the array class. I am wondering if the length variable in arrays is defined

Answer 1

For every Array we declare, corresponding classes are there in Java but it's not available to us.You can see the classes by using getClass().getName()

    int[] arr=new int[10];
    System.out.println(arr.getClass().getName());

Output : [I

where "[" represents one dimension array and "I" represents Integer. Similarly, we can have

    [F for one-dimensional float arrays
    [Z for one-dimensional boolean arrays
    [J for one-dimensional long arrays
    [[I for two-dimensional int arrays

and so on.
