abstract class java
Abstract classes have some special features:
it's impossible to create an instance of an abstract class;
an abstract class can contain abstract methods that must be implemented in non-abstract subclasses;
it can contain fields and non-abstract methods (including static);
an abstract class can extend another class, including abstract;
it can contain a constructor.Java Abstract Class and Method
abstract class Language {
// method of abstract class
public void display() {
System.out.println("This is Java Programming");
}
}
class Main extends Language {
public static void main(String[] args) {
// create an object of Main
Main obj = new Main();
// access method of abstract class
// using object of Main class
obj.display();
}
