Local Data Storage 4 – Java Fixed Width Text files using row, col type storage.

This article demonstrates using a fixed field width | delimited text file similar to a spread sheet. You can store and retrieve various data types in give row,col cells. It expands columns if new data is longer than the cell. It does not add new columns or rows however and if you try to access columns or rows that are no there you get out of bounds errors. In the example I show a survey note book sheet that we use in mapping caves. A future version of this might calculate variables that would be used in cave mapping and add them to the sheet. This could also be used for mapping things above ground.
