A class can have static variables and methods. Static methods and variables are associated with class itself and are n't tied to any specific object. Hence statics can be accessed without instantiating an object. Static methods and variables are usually accessed by class name.

Non static methods and instance variables aren't accessible inside a static method since no this reference is available inside a static method.
