Is Java single inheritance?
The class based on the parent class is called a child class (or subclass or derived class.) In Java, (unlike with humans) children inherit characteristics from just one parent. This is called single inheritance. Some languages allow a child to inherit from more than one parent.
Is overriding possible in Java?

Why inheritance is used in Java?
The idea behind inheritance in Java is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you can reuse methods and fields of the parent class. Moreover, you can add new methods and fields in your current class also.

What is overloading and overriding?
Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters.
Why is @override used in Java?
