Java overloading vs overriding

Question

Hi I just want to make sure I have these concepts right. Overloading in java means that you can have a constructor or a method with different number of arguments or differe

Answer 1

Correct; overloading is providing multiple signatures for the same method.

Overriding, which is what I think you mean by "overwriting" is the act of providing a different implementation of a method inherited from a base type, and is basically the point of polymorphism by inheritance, i.e.

public class Bicycle implements Vehicle {
    public void drive() { ... }
}

public class Motorcycle extends Bicycle {
    public void drive() {
        // Do motorcycle-specific driving here, overriding Bicycle.drive()
        // (we can still call the base method if it's useful to us here)
    }
}
