Passing Value to Methods In Java, variables are always passed by copy! Passing to a method by copy:Method receives a copy of the variable. Passing to a method by reference:Method receives a reference of the original object. Pass By copy Copy only works in the local area, while keep uncha...
In case of primitives, the value is simply copied inside stack memory which is then passed to the callee method; in case of non-primitives, a reference in stack memory points to the actual data which resides in the heap. When we pass an object, the reference in stack memory is copied a...

Well, the keyword 'this' means the 'the current object in execution. That means the object using which you invoke this method, will be referred in the method. That's when the 'this' helps assigning the incoming values to the actual set of variables of the object which is in execution...
If an actual parameter is a reference to an object, then the reference value is passed. This means that both the actual parameter and the formal parameter are aliases to the object denoted by this reference value during the invocation of the method. In particular, this implies that changes ma...
