arrays are passed to a method by ____

When an array is passed to a method as a reference?
When you pass an array to other method, actually the reference to that array is copied.
Any changes in the content of array through that reference will affect the original array.
But changing the reference to point to a new array will not change the existing reference in original method.
What does a method receives when an array is passed to it?
Answer.
When an array is passed to a method, the method receives a reference to the array.
Note: In Java, a pointer value to the memory address location is used, making arrays "pass-by-value" (and not actually "pass-by-reference" as seen in C++.) You can pass an entire array, or a single element from an array, to a method.

What is passed in array?

The address of the first variable is passed when you pass an array to a function in C.
An array passed to a function decays into a pointer to its first element.

Arrays can be passed to other methods just like how you pass primitive data type's arguments. To pass an array as an argument to a method, you just have to pass the name of the array without square brackets. The method prototype should match to accept the argument of the array type.
