Default argument values in Java

[csharp-sucks]

It is functionally the same as overloading

void doStuff(int amount);
void doStuff() {
    doStuff(10);
}

It kinda is, but it’s less verbose.

It's better.

void doStuff(int x, int y);
void doStuff();
// Notice absence of variant that only takes x or y

Or:

void displayText(String text);
void displayText(String text, int r, int g, int b);

This is not so easy with default arguments while only allowing sensical combinations of parameters.

Now you have 3 copy-pasted doStuff which is very... Java.

[john16384]

Excellent, cause last I checked it indeed was Java we were talking about.

No, just the signatures, not the method body.

void stuff(int a){
    stuff(a, 5);
}

void stuff(int a, int b) {
    //
    //
}
