Static means one per class, not one for each object no matter how many instance of a class might exist. This means that you can use them without creating an instance of a class.Static methods are implicitly final, because overriding is done based on the type of the object, and static methods are attached to a class, not an object. A static method in a superclass can be shadowed by another static method in a subclass, as long as the original method was not declared final. However, you can't override a static method with a nonstatic method. In other words, you can't change a static method into an instance method in a subclass.

Hi Monu,

Class methods are methods which are declared as static. The method can be called without creating an instance of the class.

A static variable is associated with the class as a whole rather than with specific instances of a class.

Methods declared with the keyword static as modifier are called static methods or class methods. They are so called because they affect a class as a whole, not a particular instance of the class. Static methods are always invoked without reference to a particular instance of a class.
Note:The use of a static method suffers from the following restrictions:
·    A static method can only call other static methods.
·    A static method must only access static data.
·    A static method cannot reference to the current object using keywords super or this.

Thanks
