I've got a file from a vendor that has 115 fixed-width fields per line. How can I parse that file into the 115 fields so I can use them in my code?
My first thought is just to make constants for each field like NAME_START_POSITION and NAME_LENGTH and using substring. That just seems ugly, so I'm curious about better ways of doing this. None of the couple of libraries a Google search turned up seemed any better, either.

getFormat(). setPadding('_'); // creates a fixed-width parser with the given settings FixedWidthParser parser = new FixedWidthParser(settings); // parses all rows in one go. List<String[]> allRows = parser. parseAll(new File("path/to/fixed.
Data in a fixed-width text file is arranged in rows and columns, with one entry per row. Each column has a fixed width, specified in characters, which determines the maximum amount of data it can contain. No delimiters are used to separate the fields in the file.
ParseFile is a local representation of a file that is saved to the Parse cloud. The workflow is to construct a ParseFile with data and optionally a filename. Then save it and set it as a field on a ParseObject .
I would use a flat file parser like flatworm instead of reinventing the wheel: it has a clean API, is simple to use, has decent error handling and a simple file format descriptor. Another option is jFFP but I prefer the first one.

I've played arround with fixedformat4j and it is quite nice. Easy to configure converters and the like.
