5.Write a Java program to create an abstract class Employee with abstract methods calculateSalary() and displayInfo(). Create subclasses Manager and Programmer that extend the Employee class and implement the respective methods to calculate salary and display information for each role. Click me to ...
public abstract class MyAbstractClass { } That is all there is to declaring an abstract class in Java. Now you cannot create instances of MyAbstractClass. Thus, the following Java code is no longer valid: MyAbstractClass myClassInstance = new MyAbstractClass(); //not valid If you try...

1. Abstract Class In Java, anabstract class cannot be instantiateddue to its partial implementation, but it can be extended just like a normal class. When an abstract class is inherited, the subclass usually provides implementations for all of theabstractmethods in its parent class. However, if...
