    // POINTS REMEMBER : 
    // 1. Method name same but type of parameters, 
    // number of parameters and 
    // order of parameters must be different.
    // 2. Return type alone can not overload the method.
    // 3. Static and not-static methods can be overloaded.
    // 4. Constrcutor can be overoaded but diffrent parameters.
    // 5. Its compile time polymorphism because compiler decides 
    // which methods to call during compilation based on the argument passed.
