In Java, all method parameters, whether primitive types or object references, use the call-by-value mechanism. This means that a copy of the variable's value is passed into the method. For primitive types, the actual value is passed. For objects, the reference (or "pointer") to the object is passed by value, meaning that the method receives a copy of the reference.
