What are the two ways to call a static method in Java?

Static methods have keyword ‘static’ before the method name, belong to the class and not the instance, and can be accessed through the class name. They can call other static methods and access static attributes directly but need an instance to access class attributes and methods.

How do you reference a static method in Java?

Can we override static method?

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

What are static methods?

A static method (or static function) is a method defined as a member of an object but is accessible directly from an API object’s constructor, rather than from an object instance created via the constructor.

When should you use a static method?

We cannot access directly instance variables from a static method. Therefore, to access an instance variable, we must have an instance of the class from which we access the instance variable.

Is overriding possible in Java?

In Java, methods are virtual by default. We can have multilevel method-overriding. Overriding vs Overloading : … Overriding is about same method, same signature but different classes connected through inheritance.
