What is the term used to define the values that are common across all instance of class?
Variables
are properties an object knows about itself. All instances of an object have their own copies of instance variables, even if the value is the same from one object to another.
Is common to all the instances objects of the class?
Class variables
, often referred to as static variables, are shared across all instances of a class. Every instance points to same value and any changes are seen by all.
What is the term used to define the values that are common across all instances of a class?
Variables are properties an object knows about itself. One object instance can change values of its instance variables
What defines the state of an object in Java?
State is
a behavioral design pattern that allows an object to change the behavior when its internal state changes
. The pattern extracts state-related behaviors into separate state classes and forces the original object to delegate the work to an instance of these classes, instead of acting on its own.

What does a class contain?

data field descriptions (or properties, fields, data members, or attributes)
. These are usually field types and names that will be associated with state variables at program run time; these state variables either belong to the class or specific instances of the class.
What are the instances of a class?
16 Answers. A class is a blueprint which you use to create objects.
An object
is an instance of a class – it’s a concrete ‘thing’ that you made using a specific class. So, ‘object’ and ‘instance’ are the same thing, but the word ‘instance’ indicates the relationship of an object to its class.
What is Java static?
In the Java programming language, the keyword static indicates
that the particular member belongs to a type itself
, rather than to an instance of that type. This means that only one instance of that static member is created which is shared across all instances of the class.
What is the state of an object explain with an example?
