항해99 워밍업 4일차

• 오늘 공부한 것
  - JAVA Class 구현 실습
  
  
• 고민했던 문제
  - Interface의 메서드를 여러 개의 상속 클래스에서 구현할 때 공통되는 코드를 줄일 수 있는 방법은?
  

  public interface Walkable {
      void walk(int x, int y);
  }
  
  public class Child extends Person implements Walkable, Runnable, Swimmable {
      
      @Override
      public void walk(int x, int y) {
          whoIs();
          System.out.println("speed: " + speed);
          this.x = x;
          this.y = y;
          System.out.println("walked to: " + getLocation());
      }
  }
  
  public class Parent extends Person implements Walkable, Runnable {
  
      @Override
      public void walk(int x, int y) {
          whoIs();
          System.out.println("speed: " + speed);
          this.x = x;
          this.y = y;
          System.out.println("walked to: " + getLocation());
      }
  }
      
  public class GrandParent extends Person implements Walkable {
  
      @Override
      public void walk(int x, int y) {
          whoIs();
          System.out.println("speed: " + speed);
          this.x = x;
          this.y = y;
          System.out.println("walked to: " + getLocation());
      }
  }
