When space for an array is allocated, the array size must be given, to specify the number of elements Java uses pass by value to pass arguments to a method

For example, let's say we define an array of type byte of size six: byte[] a = new byte[6]; Since Java allocates 4 bytes for an integer, and we define our array as: In the following example, the function changes array element 0 to 10, and this
