Answer / prs01

Pass by value.
1. When passing primitives, it passes a copy of the
variable to the method. Any change made in the method does
not reflect in the calling method.
2. When dealing with objects, a copy of their
reference/address is passed. Thus the change made to the
object is reflected in the calling method.

Answer / sujini

java pass arguments only pass by value

Answer / mr.h

In Java no matter what type of argument you
pass the corresponding parameter (primitive variable or object reference) will get a copy of that data, which is
exactly how pass-by-value (i.e. copy-by-value) work.

In Java, if a calling method passes a reference of an object as an argument to the called method then the passedin
reference gets copied first and then passed to the called method. Both the original reference that was
passed-in and the copied reference will be pointing to the same object. So no matter which reference you use, you
will be always modifying the same original object, which is how the pass-by-reference works as well
