Object is a superclass for every java class because all classes required the
properties of object if you create a class

java.lanag.Object fully classified class name

Because every class is subclass of object you can place user defined objects
in collection frame work classes. if object is not a super class then you cannot
put your object in collection classes ed: they void method signature

public void add(Object 0)

If you are using this method you can place your objects because your class
derived from  object class and also wait notify notify all methods used in
threading and String to String() method you have to override to display object
as string

int hasgCode to get hascode if you override this methods then only you can
add your class in Hash table object, for component oriented programming toString
and hascode must be overrided derived from Object class

Every class in the Java system is a descendent (direct or indirect) of the Object class. The Object class defines the basic state and behavior that all objects must have, such as the ability to compare oneself to another object, to convert to a string, to wait on a condition variable, to notify other objects that a condition variable has changed, and to return the object's class.

java is an object oriented language and in java everything is represented as objects (except for primitives, for programmers ease) and therefore all the classes must inherit the features of an object...... and hence object class is the parent of every class.

Because, Java soft people wanted Hirarichy to maintain.
There should not be 2 base classes, as it leads confusion to the programmar, so every class is child of Object.

Because it has methods like useful for all the classes, like wait, notify, notifyall, clone and gc, these methods are common use for all classes.

The main reason is Inheritance. If you observe the methods in Object class, contains the basic methods that every class should contain and they are very basic features or functionalities that every class should have and support.

Also there are many reasons for that...
