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
Yes, the base class for all other Java classes is Object.
The top level class in Java is "Object." All other classes are subclasses of Object by default.
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.
That's the name used in Java for inheritance. It means that one class has all the behavior of another class; additional functionality can be added to the derived class.
Fields and methods. Fields are variables defined at the class level, i.e., they are available for all methods. Methods are the equivalent of functions / procedures, but they are defined for a specific class.
All Java classes with no defined superclass, extend from java.lang.Object.
All classes in java must inherit from the Object class
Yes, the base class for all other Java classes is Object.
The answer to this is related to the idea of inheritance in general - the idea of inheritance is that you define a common set of behaviors, that apply to all subclasses. Anything defined in the "Object" class is available to all classes you create. Look in the documentation for the description of the "Object" class, to see what methods are available in all Java classes.
Because, that is how all Java classes work. When a class is initialized/created all the classes it extends from (its super classes) need to be initialized as well.

object class is a super class for all other class...
class is a blueprint which does not have its own existence but it can pass all of its feature to its child classes.
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 is the topmost class in the class hierarchy. Classes inherit directly from this class by default; all classes inherit from Object directly or indirectly.
Java classes can have practically any size. It all depends on how much information they store.
It's part of the language specification that all objects in Java must inherit from Object. Java defines a strict class hierarchy, and enforcing a "super most class" ensures that this ordering is maintained.
