Method Overloading

Method Overloading In Java :

Method overloading in Java allows a class to have multiple methods with the same name but with different parameters. The Java compiler distinguishes between these overloaded methods based on the number and types of parameters they accept. This allows you to create more versatile and flexible classes by providing multiple ways to use a method with the same name.

Key points about method overloading in Java:

• Method name must be the same: In method overloading, the method names must be the same, but the parameter lists should be different

• Parameter lists must differ: The parameter lists of overloaded methods must differ in one or more of the following ways:
  

                     The number of parameters

                     The data types of the parameters

                     The order of the parameters

• Return type is not considered: Overloaded methods can have different return types, but the return type alone is not sufficient to differentiate them. The compiler relies on the method's name and parameter list to determine which version of the method to call.

Here's an example of method overloading in Java:

In this example, the MathOperations class contains three overloaded add methods. Each method has a different parameter list, allowing you to call the appropriate method based on the arguments provided. The method with the matching parameter list is determined at compile time.

Why it is important ?  

Method overloading is important in Java due to several reasons:

• Readability and Maintainability 
• Flexibility and Convenience 
• Code Reusability
• Avoiding Naming Conflicts
• Simplifying Maintenance   etc.
