can we have abstract class having no abstract method in java?
abstract class AbstractDemo { // Abstract class
private int i = 0;
public void display() { // non-abstract method
System.out.print("Welcome to Tutorials Point");
}
}
public class InheritedClassDemo extends AbstractDemo {
public static void main(String args[]) {
AbstractDemo demo = new InheritedClassDemo();
demo.display();
}
}Is it mandatory for an abstract class to have abstract methods?
No, abstract class can have zero abstract methods.can you declare an abstract method in a non abstract class
No. A normal class(non-abstract class) cannot have abstract methods.Copyright © 2021 Codeinu
