Overloading methods

• Each method has a signature.
• The signature is (a) the name together with (b) the number and (c) types of parameters.
• Two methods in the same class can have the same name if they have different numbers or types of parameters.
• This capability is called overloading.
• The compiler compares the number and types of parameters to find the method that matches the signature.
• The signature does not include the return type or list of thrown exceptions, and you cannot overload based on these factors.

    public void aMethod(String s) {}
    public void aMethod() {}
    public void aMethod(int i, String s) {}
    public void aMethod(String s, int i) {}
