What is Method Overloading:
Method overloading is a one of the feature in Java that allows us to create multiple methods with the same name but with different parameters. This means that we can have multiple methods with the same name, but Java can differentiate between them based on their parameters.
Creating Method Overloading:
To understand how method overloading works, let's consider an example. We can have a class called "Calculator" that has a method called "add". We can overload this method by creating another method with the same name but with different parameters. For example, we can create a method called "add" that takes two integers as parameters, and another method called "add" that takes two doubles as parameters.
When we call the "add" method, Java will look at the number and types of the arguments that we have passed to the method and select the appropriate method to execute. This is called compile-time polymorphism, where the Java compiler decides which method to call based on the method signature.
look at the example:
And the Output is:

16.0
Method overloading works within a single class or across multiple classes in the same package. This means that we can have multiple methods with the same name and different parameters in the same class or in different classes in the same package.
Use of the parameter:
The use of method overloading is to provide a convenient way to define methods that perform similar tasks but with different input parameters. This makes our code more readable and reduces the amount of code we need to write.
For example, we can have a method called "SumoftheNumbers" that can take different parameters as Numbers that we want to add. By overloading the method, we can use the same method name but provide different parameters to calculate the sum of different numbers.
Method overloading makes our code more readable and reduces the amount of code we need to write.
