Thread: file input to two dimensional array

    Default file input to two dimensional array

    I am trying to input file contents into a two dimensional int array. The file consists of multiple rows and columns of chars. I have to apply an if/then to convert the chars to integers, but before I do that, I need to be able to read through the chars in one line, then the next...

    I know how to loop through with hasNextLine, but that only gives me the line as a string and not each char.

    The file looks like this:

    ------..
    ...-----
    ........
    -------

    How do I get the value of each char so I can apply the if/then to dump values into the integer array?

    Should I take each row as a string and parse the chars that way? If so, how?

    Any help would be greatly appreciated.

    How do I get the value of each char
    If you read each line into a String, the String class has methods to get each character in the String.
    If you don't understand my answer, don't ignore it, ask a question.
