An abstract class is a type of class that can only be used as a base class for another class  such thus cannot be instantiated  To make a class abstract  the keyword abstract is used  Abstract classes may have one or more abstract methods that only have a header line  no method body   The method header line ends with a semicolon      Any class that is derived from the base class can define the method body in a way that is consistent with the header line using all the designated parameters and returning the correct data type  if the return type is not void   An abstract method acts as a place holder  all derived classes are expected to override and complete the method   Example in Java  abstract public class Shape     double area   public abstract double getArea
