public class Box {
   int height = 5; // Initializing variables of Box
   int width = 10;
   int depth = 5;

   public void Change_Box_Value(int h, int w, int d) { // method of changeing height, width, and depth
      this.height = h;
      this.width = w;
      this.depth = d;  
   }

   public void Info_Box() { // method of Showing infos of Box
      System.out.println("height of box : " + height + ", width of box: " + width + ", depth of box: " + depth);
   }

    public static void main(String[] args) {
      Box shoeBox = new Box(); // Creating Constructors
      Box cookieBox = new Box();
      Box fruitBox = new Box();
     
      System.out.print("shoeBox>> "); // Info of shoeBox
      shoeBox.Info_Box();     
      System.out.print("cookieBox>> "); // Info of cookieBox
      cookieBox.Info_Box();  
      System.out.print("fruitBox>> "); // Info of fruitBox
      fruitBox.Info_Box();  

      fruitBox.Change_Box_Value(10, 10, 10); // changing value of fruitBox
      System.out.println("Volume of fruitBox: " + fruitBox.height * fruitBox.width * fruitBox.depth); // Printing volume of fruitBox
   }
}  

위에는 제가 짠 코드이고..

물어볼거는 밑에 각 문항의 답인데 이게 맞는건지 좀 봐주세요
(1) 지역변수 > h, w, d
(2) 멤버변수 > height, width, depth
(3) 멤버메소드
      void Change_Box_Value(int h, int w, d) {}, void Info_Box() {}
