Every object is an instance of some classes. You and me are 2 instances of Human class.
Sometimes developers get confused about class and objects. Developers see the code how an instance will behave from the class definition, and "thought" the class is the object, or the object is the class. It is like "I am a Human, and hence a Human is me. Or, 1 is an instance of int, and hence an int is 1. (Then what about 0, 2, 3, -1, ....)"

Each instance of a class in Active Directory is called?
Object
What does instance field mean in Java?
Fields defined without the "static" keyword.Their value is unique to each instance (object) of a class.AnswerInstance variable is a variable declared within the class for which every object of the class has its own value.
What is true when a derivation inherits both a virtual and non-virtual instance of a base class?
Each derived class object has base objects only from the non virtual instance
What is instance?
An individual object of a certain class. While a class is just the type definition, an actual usage of a class is called "instance". Each instance of a class can have different values for its instance variablesA case or occurance of something.
What are Instance variables java?
Instance variableA variable, part of an Object. These might better be called perObject variables since each instantiated object of this class will have its own private copy of this variable. They are allocated when the object is allocated via new. Static methods may not access the instance variables of their class (or any other class for that matter), other that via some object reference, e.g. anObject.someField. Static methods may even access private instance variables in their class via some object reference.
What is the definition of instances?
One can have an instance of a class or a particular object. The instance is the actual object created at runtime. In programmer jargon, the Lassie object is an instance of the Dog class. The set of values of the attributes of a particular object is called its state. The object consists of state and the behaviour that's defined in the object's class.
When programmers need to create several different examples of a class each is known as an object?
Yes. A class is simply the definition of a user-defined type, much like int and char are definitions of primitive types, whereas an object is a specific named instance of a class type, just as a named int or char variable is an instance of a primitive type.
What is the use of static method?
Static methods are not specific to each instance of a class. This allows you to have functions which return the same output for the same input for each instance of the class.
What is difference between instance variable and class variable in java?
The main difference between the class variable and Instance variable is, first time, when class is loaded in to memory, then only memory is allocated for all class variables. Usually static variables are called class variables. These variables are available throughout the execution of the application and the values are common to the class. You can access them directly without creating an object of the class. Instance variables are normal variables declared in a class, that would get initialized when you create an instance of the class. Every instance of the class would have a copy of the variable and you need a class instance (object) to access these variables
What is the meaning of instantiate in java?
Instantiate means to create an actual instance of a Class. That is, the creation of an Object of that Class. This allocates memory on the heap for that object. Instantiate creates a unique object of that class, complete with its own copy of any class variables. Thing of a Class as a design spec, which, when instantiated, creates an actual thing of that type. For instance, imagine a set of blueprints detailing how a Ford Focus auto is to be manufactured. This is a Class. When those blueprints are manufactured (instantiated, in Java-speak), the result is a physically unique car. A class can be instantiated hundreds or thousands of times, but each instantiation creates a new and unique object, in the same way the Ford Focus blueprints can result in many individual cars. In essence, it happens whenever you call: new <ClassName>();
What statement about the mass of an object is FALSE?
Each of the "following" statement is neither true nor false.
What is the definition of upper class limits?
The upper class limits are the greatest value for each class. For instance if your class is 10-20, the upper class limit is 20.
