Java program for Single level Inheritance

 Single level inheritance program in Java

//Java program for single level inheritance

class Abaseclass //Base class definition
{
    void show() //Base class show method
    {
        System.out.println("This is the show method of Base class 'A'");
    }
}
class Bderivedclass extends Abaseclass //Derived class definition
{
    void show() //Derived class show method

    }
}
class singlelevelmainclass //Main class from where the execution will start
{
    public static void main(String args[]) // Main method of main class
    {
        Abaseclass a = new Abaseclass(); // Object creation of base class
        Bderivedclass b = new Bderivedclass(); // Object creation of derived class
        a.show(); //base class method show is called by the object of base class
        b.show(); //derived class method show is called by the object of derived class
    }
}

//Save the above code as singlelevelmainclass.java
//Output of the above code :
//This is the show method of Base class 'A'
//This is the show method of Base class 'B'
