Are parameters passed by reference or passed by value in method invocation?
In programming, there are two ways to pass arguments to a method, pass-by-value and pass-by-reference: When you have a pass-by-value parameter, a copy of the argument is stored into the memory location allocated for the formal parameter. In this case, any changes made to the formal parameter inside the method will not affect the value of the argument back in the calling method. When a parameter is pass-by-reference, the memory address of the argument is passed to the method, making the formal parameter an alias for the argument. This means that changes made to the formal parameter inside the method will be reflected in the value of the argument when control is returned to the calling function. Technically, all parameters in Java are pass-by-value. All primitives are pass-by-value, period. When a primitive value is passed into a method, a copy of the primitive is made. The copy is what is actually manipulated in the method. So, the value of the copy can be changed within the method, but
