Call by Value and Call by Reference in java
Call by Value:
“Call by Value” in java means that argument’s values are copied and are passed to the parameter list of a method.
If we call a method passing a value, it is known as call by value. The changes being done in the called method, is not affected in the calling method.
Call by Reference:
“call by reference” means passing a reference(i.e. address) of the object by value to a method.
When we pass a variable of class type as an argument to a method, actually, a copy of a reference(address) to an object is passed by value to the method, not a copy of the object itself. This is because java does not copy the object into the memory.
