Each class or attribute that you add to the Active Directory schema should have a valid what?
OID, page 48 of the book we all have for this class, WIndows Server 2008 Active Directory Configuration.
WHAT IS A specific instance of a class is called?
Specific instance of a class is called object of that class.
What contains the roles and definition that use for creating and modifying object class and attributes within active direct?
The Active Directory is what contains the roles and definitions. This is what creates and modify object class and attributes.
What is the difference between a class method and an instance method?
Instance methods can be called by the object of a Class whereas static method are called by the Class. When objects of a Class are created, they have their own copy of instance methods and variables, stored in different memory locations. Static Methods and variables are shared among all the objects of the Class, stored in one fixed location in memory.Static methods cannotaccess instance variables or instance methods directly-they must use an object reference. Also, class methods cannot use the this keyword as there is no instance for this to refer to.
What method can be called without the instance of a class?
static method
What is parent class in java?
Object Class is the parent class of all classes in java.Every class in the Java system is a descendant (direct or indirect) of the Object class.
What are destructor in java?
Destructors in Java are called finalizers. Every class can define a finalize() method that will get called automatically by the garbage-collector when an instance of the class gets garbage-collected. Finalizers are not guaranteed to get called, as the instance might never get collected.
What is difference between an instance variable and a class variable?
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;
Is object of superclass created when object of derived class is created?
Not as a separate instance. The derived class instance can be used anywhere a superclass instance is expected, so it is an instance of the superclass in that respect, and a superclass constructor will be called at creation time. However, it will always act like an instance of the derived class, even if it is explicitly cast to the superclass. So overridden methods will always call the derived class method, regardless of how an outside caller refers to the 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 do you mean by Get instance?
It means create an object for a class. Instance refers to the obj of a class.
What is directory schema?
The Active Directory schema defines the kinds of objects, the types of information about those objects, and the default security configuration for those objects that can be stored in Active Directory. The Active Directory schema contains the formal definitions of all objects, such as users, computers, and printers that are stored in Active Directory. On domain controllers running either Windows 2000 or Windows Server 2003, there is only one schema for an entire forest. This way, all objects that are created in Active Directory conform to the same rules. The schema has two types of definitions: object classes and attributes. Object classes such as user, computer, and printer describe the possible directory objects that you can create. Each object class is a collection of attributes. Attributes are defined separately from object classes. Each attribute is defined only once and can be used in multiple object classes. For example, the Description attribute is used in many object classes, but is defined only once in the schema to ensure consistency.
