What is advantage of method overloading?

The main advantage of this is cleanlinessof code. Method overloading increases thereadability of the program.

Why static methods are bad?

The reason you are warned away from static methods is that using them forfeits one of the advantages of objects. Objects are intended for data encapsulation. This prevents unexpected side effects from happening which avoids bugs. Static methods have no encapsulated data* and so don’t garner this benefit.

Can we override static method?

What are the advantages of using methods in Java?

Methods allow us to reuse the code without retyping the code. In Java, every method must be part of some class which is different from languages like C, C++, and Python. Methods are time savers and help us to reuse the code without retyping the code.

What is the advantage of static method in Java?

If you apply static keyword with any method, it is known as static method. A static method belongs to the class rather than the object of a class.

Why do we need static method?

A static method has two main purposes: For utility or helper methods that don’t require any object state. Since there is no need to access instance variables, having static methods eliminates the need for the caller to instantiate the object just to call the method.
