A static variable is initialized when the class is loaded at runtime. Similarly, a class can have static methods that belong only to the class, and not to any objects of the class. Static variables and static methods are collectively known as static members, and are distinguished from instance members in a class definition by the keywordstatic in their declaration. 4 shows the class diagram for the classCharStack. It has been augmented by two static members that are shown underlined. 2. The field counter is a static variable declared at (1).

The fields of an object are called instance variables. The values of the instance variables in an object comprise its state. Two distinct objects can have the same state, if their instance variables have the same values. The methods of an object define its behavior. These methods are called instance methods. It is important to note that these methods pertain to each object of the class.
Com to register it. 3 Objects Class Instantiation The process of creating objects from a class is called instantiation. An object is an instance of a class. The object is constructed using the class as a blueprint and is a concrete instance of the abstraction that the class represents. An object must be created before it can be used in a program. In Java, objects are manipulated through object references (also called reference values or simply references). The process of creating objects usually involves the following steps: 1.
