An Java program using inheritance

An Java program using inheritance :

class BaseA
{
    public BaseA(){
       
        System.out.println("Base A constructor");
    }
   
    public void methodOne(){
        System.out.println("Method one in base A");
    }
}

class BaseB extends BaseA{

    public BaseB(){
        super();
        System.out.println("Base b constructor");
    }
    public void methodOne(){

        BaseA ba=new BaseA();
        ba.methodOne();
        System.out.println("Method one in base B");
    }
}

public class Base{
   
    public static void main(String args[])
    {
        BaseA ba=new BaseB();
        BaseB bb=new BaseB();
        ba.methodOne();
        bb.methodOne();
        Base base=new Base();
       
       
    }
    public static void main(String args[][])
    {
        BaseA ba=new BaseA();
    }
}
