Question

Suppose a method has a Location parameter called x, and the body of the method activates x.rotate90( ). When the method is activated, what happens to the argument that corresponds to x?

Answer 1

A method with a Location parameter called x that calls x.rotate90() will rotate the Location object associated with x by 90 degrees. The actual change depends on whether the Location object is mutable and how the rotate90 method is implemented.

Step-by-step explanation:

When a method with a Location parameter called x is activated, and within its body x.rotate90() is called, the argument that corresponds to x undergoes a transformation. Specifically, rotate90 implies a 90-degree rotation. Assuming rotate90 mutates the object, the original object that was passed as the argument to the method will be rotated by 90 degrees. If the method performs a rotation without mutation, then a new object may be created and the original object remains unchanged. In the context of programming, such behavior would depend on whether Location is a mutable type and on the specific implementation of the rotate90 method within the Location class.
