simple explanation of method overloading code example

Example: What's method overloading

Overloading mean same method name and different parameter, 
it can happen in same class. it's a feature that 
allows us to have more than one method with same name.

Example: sort method of Arrays class
Arrays.sort(int[] arr)
Arrays.sort(String[] arr)
....
Method overloading improves the reusability and readability. 
and it's easy to remember 
(one method name instead of remembering multiple method names)
