class extending weirdy

I'm not sure if this is a bug or something i'm doing wrong so i'm putting it in syntax. When I try to extend a class that already has a constructor, P5 gives me an error and says that i should use the parent class's constructor.. It's weird, try it out
Code:void setup() {}
void loop() {}
class Fostermom extends Hoops
{
Fostermom(float earrings, String yell, int vodkas)
{
}
}
class Hoops
{
Hoops(float howmany, boolean yoyoyo)
{
}
} |

If you take all of the inputs out of Hoops it'll work tho..

when java constructs a class it implicitly calls super() as the first call...the default constructor of its super class (this is how all objects descend from Object...super() calls all the way to the top).
youve made a class that overrides the default constructor, so you have to explicitly call it as the first line:
Code:Fostermom(float earrings, String yell, int vodkas) {
super(someFloat, someBool);
...
}

Okay I guess that makes sense.. Actually it's pretty convenient.
THanks justo!
