Java wdt class finished reads & writes

[danielrhodea]

:wave: Here it is my finished WDT java class, it's perfect for my needs!

Usage:
!!!Obviously include in your project and add to namespace to reflect directory structure
WDT wdt = new WDT("absolutefilepath",true);//auto opens wdt
WDT wdt = new WDT("absolutefilepath",false);//needs wdt.read() to open
wdt.debugMode() // toggles tracing of info
wdt.setActive(row,col); // sets an adt tile to become active
wdt.setInactive(row,col); // sets an adt tile to become inactive
wdt.write(filename); // writes to file (try not to overwrite it's untested and may break the file)

NOTE: Always keep a backup of the file!

{
	private boolean[] fileperms = {false,false};

does it work for a mac?

[danielrhodea]

untested as I d not have a mac but it should because it's a java class (it's not a standalne program as such but it would be rather easy to make into one)

java is not a compiled language as such and should make it multi-platform

WTF I can see ldz I have contributed to this website, why am I branded a leecher, this code works and is 100% mine ???

You start off as a leecher until you have ~15? rep, at which point you become an Active Member.
