我需要读取的文本文件

You are in a dark cave. In the middle, there is a cauldron boiling.
With a clasp of thunder, three witches suddenly appear before you.
Room 1 (always)
--
The witches speak in unison:
 "Mortal, we have summoned thee, make haste!
 And go forth into the farrow'd waste.
 Find eye of newt, and toe of frog,
 And deliver thus to this Scottish bog.
 Lizard 's leg, and owlet's wing,
 And hair of cat that used to sing.
 These things we need t' brew our charm;
 Bring them forth -and suffer no 'arm.
 Leave us and go!
 'Tis no more to be said,
 Save if you fail, then thou be stricken, dead."
 Room 1 (first)
--
The witches stand before you, glaring; they seem to be expecting
something from you.
Room 1 (after)
--
The witches look at your items with suspicion, but decide to go
through with the incantation of the spell:
 "Take lizard's leg and owlet's wing,
 And hair of cat that used to sing.
 In the cauldron they all shall go;
 Stirring briskly, to and fro.
 When the color is of a hog,
 Add eye of newt and toe of frog.
 Bubble all i' the charmed pot;
 Bubble all 'til good and hot.
 Pour the broth into a cup of stone,
 And stir it well with a mummy's bone."
You take the resulting broth offered to you and drink...
As the fog clears, you find yourself at a computer terminal;
your adventure is at an end.
Room 1 (win)
--
You're transported back in time … you find yourself in Georgia during
the midst of a congressional campaign.
Room 2 (always)
--
There is a campaign poster of Newt Gingrich, the Speaker of the House
of Representatives, on the wall, with his large eyes looking right at
you.
Room 2 (before item)
--
There is a defaced poster of Newt Gingrich on the wall.
Room 2 (after item)
--
You enter a room and you are blinded as soon as you enter, a flash of holy light shining
down from the ceiling, seemingly pointing towards an object of importance.
Room 3 (always)
--
Upon further inspection, there is literally nothing in the room.
Room 3 (first)
--
Still nothing here.
Room 3 (after)
--
You walked through the door way and there is what seems to be a sign for a shopping complex, 
a shopping clerk standing at at the entrance and welcoming you in. You make your way inside.
Room 4 (always)
--
There is a woman at a small makeshift stall with a single
giant chocolate covered lizard leg with a sign next to it
that says free sample. She seems to be eyeing you excitedly.
The woman begins to call you over, asking if you would like 
to take the giant chocolate covered lizard leg away from her. 
She seems desperate.

Room 4 (before item)
--
With the leg gone, you find that the stall has been destroyed and all that is left is,
a single, leg-less lizard crying on the ground.

Room 4 (after item)
--
When stepping into the hall to enter the room, a gust of wind pushes you forward,
forcing you into a room with a small, seemingly self sustaining tornado.
Room 5 (always)
--
You attempt to see if there is anything of importance within the tornado,
but all you find is some hot dogs, some papers covered in things from quantum
physics, and a small, white, very annoying dog.
Room 5 (first)
--
While you were gone, the dog started a game of poker... with itself. It seems to be losing.
Room 5 (after)
--
Nothing special about this room. Just a room. A very roomy room. Full of room.
Room 6 (always)
--
You find yourself walking into a scene where the cast of Monty
Python's Flying Circus is performing the "Crunchy Frog" sketch. You
see the confectioner as he replies, "If we took the bones out it
wouldn't be crunchy now, would it?" You're a bit creeped out.
Room 7 (always)
--
You see a box of "Crunchy Frog" chocolates, the contents of which 
contains a single nicely cleaned frog toe that has been carefully 
hand-dipped in the finest chocolate.
Room 7 (before item)
--
With the chocolate frog toe now gone, the entirety of the circus
collapses in on itself, you being the only one to survive the
desctruction, it seems.
Room 7 (after item)
--
You walk into a strangely dark room, a spotlight shining down on something particular
in the center of the room. You feel as if this time there will actually be something there.
Room 8 (always)
--
There is an owl plush sitting on a table next to a pair of scissors.
The owl's right wing is extended with a definite sort of 'cut here' line
across the base of the wing. 
Room 8 (before item)
--
There is a scream echoing across the room, blood dripping from the owl plush's
vacant wing socket. What have you done?
Room 8 (after item)
--
As you step through the time portal, your head begins to spin you're
disoriented and then awaken. You find yourself at the outside door of
a dormitory kitchen.
Room 9 (always)
--
There is a group of strange looking cats wearing crowns and standing on their
hind legs, all screaming and banging on the kitchen back door to be let in. 
The kitchen's head chef is seething with anger, tightly gripping his
cleaver.

Room 9 (before item)
--
Upon returning to the kitchen, the meowing had stopped. You knew why.
You had asked the chef to kill those cats for you so you could have a tuft
of their hair. You monster.

Room 9 (after item)
--
The final room. Though you know this doesn't signal the end of your journey, you feel accomplished to have made it this far. 
The wind is blowing through your hair, and the room carries a sense of power with it.

Room 10 (always)
--
After venturing deeper into the room, you find a very large treasure chest in the center. It flings itself open and
reveals itself to be a mimic, attacking you and taking a chunk out of your left leg. This doesn't do anything
because the programmer hasn't coded battling into this game, so it is just a minor annoyance.

Room 10 (first)
--
You're still more than just a little peeved at that whole mimic thing.

Room 10 (after)
--

我目前正在尝试用java制作一个游戏，只是为了获得乐趣和额外的编码经验，但我遇到了一个问题。基本上，descriptions.txt 文件应该包含我在游戏中的所有描述。我不想对它们全部进行硬编码，而是想从该文件中读取它们，在 -- 处分割它们并将它们添加到一个数组中(这是我的 java 类中的一位 friend 给我的所有建议) )。

事实是，我完全不知道如何去做这一切。我知道我需要一个文件阅读器，通过 stringSplit 函数和 -- 将文档分割成多个字符串，但我不知道如何将它们添加到数组中，然后如何以便稍后在游戏中实际引用它们。

我能得到的任何帮助都非常有帮助，并且非常感谢和希望任何有关清理我的代码的其他帮助。
