    Re: 2d Arrays

    You program is returning 1 because that is what you told it to do. It is apparent (based on what you've said) that your code is getting to the first return statement before the last one. Since that...

    Re: 2d Arrays

    With out actually running your code, I would assume it has to do with the "return found" inside the last for loop. (Which also seems to be missing the "for" part of it..)

    Re: Timer?

    A Timer itself does not know how to read from a text file.

    You would have to read from the text file first (See the thread "Scanner or BufferedReader" for help on that), then parse your data, and...

    Re: Scanner vs BufferedReader?

    It really doesn't matter where the input comes from. For example:

    Scanner in = new Scanner(new File("myfile.txt");

    BufferedReader in = new BufferedReader(new FileReader(new File("myfile.txt"));...

    I would still do it the way I started doing it above.

    I would make the file look like this:

    x,y:z

    where 1 is the horizontal position (the x value, or the first value in the...

    Re: Writing clone() method for LinkedList

    I am assuming that line 14 is this:

    If that's the case, then you are trying to cast a LinkedList into your OurLinkedList....

    Re: Writing clone() method for LinkedList

    Why does your clone method repeatedly (assuming size is greater than 1) add "A" into the cloned list and not the values of the list it is cloning?
  21. Re: In a bit of a pickle, unsure of what I should do

    It might be easier to use a two dimensional array here, as it more accurately represents a Sudoku square.

    Re: Substitution of Values in Array

    You need to loop through the array and check each value. If the value is of x, then change that value to y.

    Here is some pseudo code:

    if...

    Re: Scanner vs BufferedReader?

    Other than what helloworld said, Scanner internally buffers its input using a CharBuffer. Whereas a BufferedReader is meant for generic use for buffering characters from some sort of input.
