Dealing with strings (esp. leading spaces and/or end of line)

Leading spaces

The easiest way to remove leading spaces (such as a tab or blank) is to use the trim() function. So as an example:

        line = datafile.nextLine();
        line = line.trim();

Dealing with the end of line

After reading a number, if the next input is to be a string on a new line, be sure to read the rest of the current line. Example:

        number = keyboard.nextInt();
        keyboard.nextLine();
