    int persons_Kid=3; / /defining integer variable persons_Kid

    Person_details p1 = new Person_details (); / /creating Person_details class Object

    p1. Set_Num_Kids (persons_Kid); / /calling method Set_Num_Kids.

    System. out. println (p1. get_Num_Kids ()); / /calling get_Num_Kids method and print value

    p1. incNumKids (); / /calling incNumKids method

    System. out. println (p1. get_Num_Kids ()); //calling get_Num_Kids method and print value

    }

    }
