What is the base object in Java?

Object class is the super base class of all Java classes. Every other Java classes descends from Object.

Inheritance enables you to create new classes that reuse, extend, and modify the behavior defined in other classes. The class whose members are inherited is called the base class, and the class that inherits those members is called the derived class . A derived class can have only one direct base class.

The Object class is the parent class of all the classes in java by default . In other words, it is the topmost class of java. The Object class is beneficial if you want to refer any object whose type you don’t know. Notice that parent class reference variable can refer the child class object, know as upcasting.
