Question

How do we pass parameters by value in a Java method?

Answer 1

✨✨Pass by value: The method parameter values are copied to another variable and then the coppied object is passed, that is why it is called pass by value.

✨✨Pass by reference: An alias or reference to the actual parameter is passed to the method, that is why it is called pass by reference.

Answer 2

Answer:

changes made to formal parameters don't get transmitted back to the caller .Any modifications to the formal parameters variable inside the called function or method affect only the separate storage location and will not be reflected in the actual parameter in the calling environment. This method is also called as Call by Value.
