Hello, i am very new to Java, started just a couple of days before, I wanted to know why is the java.lang.Object class is the root class of all classes, is it something to do with polymorphism?

Âll java classes must have SOMETHING in common in order to use them.

Object is the most simple of all classes. It practically defines a couple of simple methods to handle a object of any kind.

Just for an example look at the class Vector.

You can add objects of any class to it. The reason is that every class is a subclass of Object. Otherwise, it would not be possible to compile the code.
