搜索文本文件并随机选择？

Question

my homework is this if more context is needed - I would explain it but it is pretty long to explain and the text files are provided on the site if people need to look at them: http://www.cis.upenn.edu/~cis110/hw/hw06/index.html

Right now I am on Step 2 and stuck on randomly choosing from the three items associated with the treasure class, checking to see if they start with "tc". I can extract the treasure class from the monster.txt file and I have the monster. This is my method for finding the treasure class:

public static void getTreasureClass(Monster monGet)
    throws FileNotFoundException{
    Random rand = new Random();
    String tc=monGet.getTreasureClass();
    Scanner file=new Scanner(new File ("TreasureClassEx.txt"));
    System.out.println(tc);
    while(!file.next().equals(tc)){
        file.next();
        }
    tc=file.next();
    if (tc.startsWith("tc:")){

    }
    else {
        System.out.println("test");
        }   
    }

It is extremely incomplete, but I would appreciate some tips on where to go next in terms of randomly choosing from the three items, or if my code is bad. Thanks in advance!

Answer 1

Makes sure that you import the things that I add, because you dont show imports i will not add them

public static void getTreasureClass(Monster monGet)
    throws FileNotFoundException{
    Random rand = new Random();
    String tc=monGet.getTreasureClass();
    Scanner file=new Scanner(new File ("TreasureClassEx.txt"));
    System.out.println(tc);
    List<String> list = new LinkedList<String>();
    while(!file.next().equals(tc)){
        file.next();
        }
    tc=file.next();
    if (tc.startsWith("tc:")){
    list.add(tc);
    }

    String treasure = list.get(rand.nextInt(list.size()));
    else {
        System.out.println("test");
        }   
    }

So in this I saved the example in the String value 'treasure'

I dont feel good helping you with your homework -_-

Answer 2

So a 'Hell_Bovine' has a Treasure Class of "tc:Cow_(H)".

So you're looking for this line in TreasureClassEx.txt

tc:Cow_(H)  tc:Act_5_(H)_Equip_B    tc:armo3    tc:armo3

Then you'll choose one of the three options at random.

And you'll keep reading the TreasureClassEx, finding the right line, and making a random choice for as long as the "treasure class" that you're looking for starts with "tc:".

For example, for "tc:Cow_(H)" you might choose "tc:armo3". For "tc:armo3", you might choose "Quilted_Armor". And then you would stop there.

At least that's how I'm reading the instructions. ;->
