This document discusses method overloading in Java. It defines method overloading as writing two or more methods in the same class with the same name but different parameters. Method overloading adds flexibility by allowing methods to accept arguments of different data types. There are two ways to overload methods: by changing the number of arguments or by changing the data type. The advantages of method overloading include using the same name for related methods and handling default parameter values.

- 4. POLYMORPHISM • Polymorphism means more than one form, same object performing different operations according to the requirement. Types • Compile time: Overloading. • Run time: Overriding.
- 5. Method Overloading • Method overloading means writing two are or more methods in the same class by using same method name, but passing the parameters is different. • Overloading is the practice of supplying more than one definition for a given method name in the same class. The compiler will automatically select the most appropriate one based on the arguments with which it is called.
- 6. Method Overloading • Overloading is useful to add flexibility to a method. In general, if you want to create a method that adds two numbers then it only take either integer, double, or float but by overloading, you can add values of all data types.
- 7. Method Overloading There are two ways to overload the method in java o By changing number of arguments o By changing the data type
- 8. o By changing number of arguments
- 9. o By changing the data type
- 10. Advantages of method overloading • It allows you to use the same name for a group of methods that basically have the same purpose. • It provides an easy way to handle default parameter value. • Assume that a method has one required parameter and two optional parameters. Three overloaded forms of this method can be defined. It can accept one, two or three parameters.
