What is abstract class in Java with example?

A class that is declared using “abstract” keyword is known as abstract class. It can have abstract methods(methods without body) as well as concrete methods (regular methods with body). A normal class(non-abstract class) cannot have abstract methods.

An abstract class, in the context of Java, is a superclass that cannot be instantiated and is used to state or define general characteristics . An object cannot be formed from a Java abstract class; trying to instantiate an abstract class only produces a compiler error.
