Java function variables with default value

Question

I have some function in java and i want this function to have a parameter with a default value that is set to variable if no value sent, look like following:

private void test(int count=5)
 {
 }

So i can call the function with 2 ways: test(); and test(10);
how do i do it?

or use Integer --> if null then initialize variable to 5 – Laurent B Oct 30 '18 at 09:29 — Laurent B, Oct 30 '18 at 09:29
@LaurentB That still requires that a null be passed ..? – WestCoastProjects Feb 07 '21 at 02:56 — WestCoastProjects, Feb 07 '21 at 02:56

5

You could have two overloaded methods. The version with no parameters would call another version accepting an int input, passing a default value of 5.

private void test() {
    test(5);
}

private void test(int count) {
    // rest of method
}
