what is the difference between pass by reference and call by reference?

java

Solution

Java does not pass any variables by reference.

It is tempting to think of objects being passed by reference in Java -- but harmful. Variables of object type are references. When passed, they are passed by value.

In other languages, pass-by-reference and call-by-reference are the same thing.

Edit: More detail is provided in the existing stackoverflow question "Is Java pass by reference?" (Spoiler: No.)
