当ArrayList位于对象内部时，访问ArrayList方法

Question

I am trying to design a text based game.

The game will have a feature in which, if the user inputs get all , all the objects in the room must be added to the player's inventory.

The inventory of the player is an ArrayList of objects and so is the room's object " sack "

The code that i have written is as follows:

public void getAll(Room room, Player player)
  {
      for(int i = 0; i < room.objectNames.size(); i ++)
      {
          player.inventoryObjects.add(room.objects.get(i));
      }
  }

This method is inside the main class, ie , the class which has the main method.

The arraylists are declared as:

public ArrayList<Objects> inventoryObjects = new ArrayList<Objects>();
//this is in the Player Class

public ArrayList<Objects> objects = new ArrayList<Objects>();
//this is in the Room Class

Can you tell me an alternative to line: 3 in the first piece of code that i have typed(the one with the loop) ?

-Thanks in advance

Answer 1

addAll方法将为您执行循环。

player.inventoryObjects.addAll(room.objects);
