Static class in java :

Static class in java :



YES, we can  have static classes in java like we've got static variables and static method and static things are related to the complete class not with an object of a class.

Static variables and methods


Static variables and methods :
Static Variable :Static variables belongs to the complete class instead of one object .
They have only one copy of memory
They can be access with simply name of class ,we don't need an object to initialize or access them
For eg . we've got a class Student as below :
public class Student{
private static String studentId;
public Static void studenttest()
{
}
So we are able to access each static method and variable as
Student.studentId
Student.studenttest()
