# Eobard
|
||||
|
||||
This task can be done in much less lines and much less visual complexity by using the "StringBuilder" class, but I wanted to build it on my own to practice writing Java, so the only thing I allowed myself to use is basic programmatic operations.
|
||||
An Java desktop application for reversing any text quickly and elegantly. Built with elementaryOS.
|
||||
|
||||
Changelog:
|
||||
|
||||
- Version 3.0:
|
||||
- Changed GUI to use "text" terminology rather than "string".
|
||||
- Completely refactored input validation to check for input comprised entirely of whitespace.
|
||||
- Added more documentation
|
||||
- Fancified input dialog boxes
|
||||
- Branded as actual application instead of practice code
|
||||
- Added TODO section
|
||||
- Added new screenshots
|
||||
|
||||
- Version 2.0 - The much unexpected release! Eobard is now completely refactored and documented. This version eliminates the need for the "ArrayList" library, and now the only non-default library used is JOptionPane. I also fixed the readme a bit.
|
||||
|
||||
- Version 1.0 - Initial Release
|
||||
|
||||
TO-DO:
|
||||
|
||||
- Polish input dialog boxes even more.
|
||||
- Handle exits (close / cancel operations) better.
|
||||
- Add custom icons and simpler install/launch procedures.
