public class Kata {

  public static boolean feast(String beast, String dish) {

    beast = beast.trim();
    dish = dish.trim();

    String beastBegin = beast.substring(0,1);
    String beastEnd = beast.substring(beast.length()-1);

    String dishBegin = dish.substring(0,1);
    String dishEnd = dish.substring(dish.length()-1);

    if(beastBegin.equals(dishBegin) && beastEnd.equals(dishEnd)){
      return true;
    }else{
      return false;
    }

  }

}
  

更有甚者

public class Kata {

  public static boolean feast(String beast, String dish) {

    return beast.charAt(0)==dish.charAt(0) && beast.charAt(beast.length()-1) == dish.charAt(dish.length()-1);

  }

}
  

public class Kata {

  public static boolean feast(String b, String d) {
    return d.startsWith(b.substring(0,0)) && d.endsWith(b.substring(b.length()-1));
  }

}
