Can I pass a primitive type by reference in Java?

Question

I would like to call a method which could potentially take on different versions, i.e. the same method for input parameters that are of type:

• boolean
• byte

Answer 1

While Java supports overloading, all parameters are passed by value, i.e. assigning a method argument is not visible to the caller.

From your code snippet, you are trying to return a value of different types. Since return types are not part of a method's signature, you can not overload with different return types. Therefore, the usual approach is:

int getIntValue() { ... }
byte getByteValue() { ... }

If this is actually a conversion, the standard naming is

int toInt() { ...}
byte toByte() { ... }
