Static Keyword in Java - Memory Management

Static Keyword

The static keyword is used for memory management mainly. It applies to variables, methods, blocks, and nested classes.

Static Variable: Gets memory only once in the class area at the time of class loading. Shared among all objects.

Static Method: Belongs to the class rather than the object of a class. Can be invoked without creating an instance of a class.

class Student {
   int rollno;
   String name;
   static String college = "ITS"; // static variable
   
   static void change() { // static method
     college = "BBDIT";
   }
}
