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.
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
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.
Object is an instance of a class. Example: In general, animal is a class where as, tiger is an object.
//Find the object in the DOM, and set its new class name: document.getElementById['elementIdName'].className = "nameOfYourNewClass";
From the Object class.From the Object class.From the Object class.From the Object class.
To find a missing dimension of an object find the size of its covering properties.
class is template of object and object is instance of a class
object class is a super class for all other class...

The formula to dertermine the size of an object using mil dots is: Distance (in yards) x height (in mils) ----------------------------------------- = size of the object in yards 1000 to find out the size of the object in inches, simply multiply your answer by 36 (because there are 36 inches in a yard)
Object is an instant of the class, by using an object we can members of the class.
There are no classes let alone objects in C. It is not an object oriented language thus all data types are primitive types. C++ is object oriented. The size of an object is equal to the sum of the non-static class member attributes, including any padding bytes required for memory alignment purposes. The size of a class is equal to the sum of the static class member attributes, plus any padding bytes required for memory alignment purpose. To minimise the need for padding bytes within the class and within objects of the class, it is best to declare all class member attributes by order of size, largest first. However, static member attributes can be declared separately from non-static member attributes since the two are allocated separately in memory.

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.
