Static

The static keyword can be used to declare fields and methods that can be accessed without having to create an instance of the class. Static (class) members only exist in one copy, which belongs to the class itself, whereas instance (non-static) members are created as new copies for each new object. This means that static methods cannot use instance members since these methods are not part of an instance. On the other hand, instance methods can use both static and instance members.

class MyCircle{   // Instance variable (one per object)  float r = 10;    // Static/class variable (only one copy)  static float pi = 3.14 F;     ...
