`Human.java`


public class Human {
    String name;
    int age;
    String country;

    void walk() {
        System.out.println("walk");
    }

    void sleep() {
        System.out.println("sleep");
    }
}

`SoccerPlayer.java`


public class SoccerPlayer extends Human {

    void run() {
        System.out.println("Run");
    }

    void kick() {
        System.out.println("Kick");
    }

    public static void main(String[] args) {
        SoccerPlayer soccer = new SoccerPlayer();

        soccer.walk();
        soccer.sleep();
        soccer.run();
        soccer.kick();
    }
}
