What is the purpose of an instance variable in Java?
An Instance variable in Java is used by Objects to store their states. Variables that are defined without the STATIC keyword and are Outside any method declaration are Object-specific and are known as instance variables. They are called so because their values are instance-specific and are not shared among instances.
What is the purpose of an object's instance variables?
Instance variables hold values that must be referenced by more than one method, constructor or block, or essential parts of an object's state that must be present throughout the class. Instance variables can be declared at the class level before or after use. Access modifiers can be given for instance variables.
What is an instance in computing?
An instance, in object-oriented programming (OOP), is a specific realization of any object. An object may be varied in a number of ways. Each realized variation of that object is an instance. The creation of a realized instance is called instantiation. Each time a program runs, it is an instance of that program.
What does an instance mean in Java?
Instance variables in Java are non-static variables which are defined in a class outside any method, constructor or a block. Each instantiated object of the class has a separate copy or instance of that variable. An instance variable belongs to a class.
