Question

How are arrays passed to methods in Java?

a) By value
b) By reference
c) By copy
d) By object

Answer 1

Arrays in Java are passed to methods by reference, meaning that the method receives the reference to the array rather than a copy. Any changes to the array within the method will therefore affect the original array.

Step-by-step explanation:

In Java, arrays are passed to methods by reference. This means that when you pass an array to a method, you are passing the reference to the array, not a full copy of the array itself. Because of this, any changes to the array within the method will affect the original array. It is important to note that Java does value semantics for primitive data types, but reference semantics for objects, and arrays in Java are treated as objects.
