    Default Re: JAVA code for deleting spaces from Text file

    Copy and edit the input file to a new file as follows:
    begin loop
    Read a line into a String and use the String class's method to replace the spaces in the String with an empty String: ""
    Write the changed line out to the new file.
    end loop
    Delete the input, rename the new file.
    If you don't understand my answer, don't ignore it, ask a question.
