What is the Difference Between pass by reference and pass by value in Java ?

Whenever an object is passed by value, it means that a copy of the object is passed. Even if changes are made to that object, it doesn’t affect the original value.

Whenever an object is passed by reference, it means that the actual object is not passed, rather a reference of the object is passed. Therefore, any changes made by an external method, are also reflected in the actual object and its reference.
