When an object reference is passed as a parameter to a method, modifying the members of that object from inside the method will result in a change to that object as seen from the client. a. True
b. False

A) True

Explanation:

Objects are known as reference types, meaning that they are always accessed by references, not copied. When a method is called, passing an object to it, Java passes a reference of that object to the method and when that reference is modified, the changes can be seen in the object itself. Therefore a mutable object can be mutated anywhere- either from where it is created or by a method it is passed to. Hence the need to always use privacy modifier keywords such as public, private or protected, to determine the exposure of class properties and methods.
