You can determine the longer name for the lowercase l LDAP object class by looking in the schema.
The instanceof keyword is used to determine if an object is of a particular class type.Example:Object obj = new String();if(obj instanceof String) {System.out.println("obj is a String!");}
Java does not have a sizeOf() operator and hence there is no way we can actually determine the size of a java class object. However we can analyze the overall heap space utilization to try to get an approximate indication of how much memory is used by an object but it is not accurate.

class is template of object and object is instance of a class
object class is a super class for all other class...
Object is the topmost class in the Java Class hierarchy. There is no Class above Object. All classes in Java are implicitly derived from Object.
The Object class, in the java.lang package, sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of the Object class. Every class you use or write inherits the instance methods of Object. You need not use any of these methods, but, if you choose to do so, you may need to override them with code that is specific to your class
Object is an instant of the class, by using an object we can members of the class.
The top level class in Java is class Object. Every other class inherits from Object and therefore Object is the top most in the class hierarchy. If you extend a class from Object such as class Animal and further extend Animal with class Dog then the hierarchy is as follows: Object | Animal | Dog Code for this hierachy is as follows: class Animal { } class Dog extends Animal { } We don't need to write class Animal extends Object because every class extends from Object so it does not need to be stated.
A class is a blueprint or a detailed description of a real-world object. An object is an instantiation of a class into memory.
A class is a collection of similar objects while an object is the individual instance of a class.
