When you define a Javaclassconstruct, the Java compiler automatically creates a constructor with no argument during the execution of the program. This means that by default, even anabstract classin Java has a default constructor that does nothing. Anabstract classcan’t be instantiated directly, so...
Abstract class in Java is similar to interface except that it can contain default method implementation. An abstract class can have an abstract method without body and it can have methods with implementation also. Here is a simple example of an Abstract Class in Java. package com.journaldev.desi...

It means that one cannot create an object of an abstract class. To explain with an abstract class example in Java: Imagine an abstract class named “Vehicle”. This class might have an abstract method called “move”. While the concept of moving is common to all vehicles, the way a car...
Abstract class is used to provide abstraction in java. An abstract class is never instantiated. Abstract classes can have Constructors, Member variables and Normal methods
1. Cannot be instantiated (new), But can have constructor 2. If a class inlcudes anabstract function, it must be defiend asAbstract class 3. Subclass must overrideabstract function 4. Abstract class could containnon-abstract function
1.Write a Java program to create an abstract class Animal with an abstract method called sound(). Create subclasses Lion and Tiger that extend the Animal class and implement the sound() method to make a specific sound for each animal. ...
