What is byvalue for java keywords?

Answer 1

There is no such keyword in Java.

In general: whether an argument is passed by value or by reference is determined by whether the argument is a primitive (by value) or an Object (by reference).

In reality, it's a little more complicated. It seems to be that the actual reference you send as an argument will not change, but the data it refers to will.

// This method will not cause a change in the original value.

void changeArg(int[] ints) {

ints = null;

}

// This method will.

void changeArg(int[] ints) {

ints[0] = 0;

}
