I don't even know why you're looping it strangely in the first place, but you wrote temp.i < thiso.rights.size() instead of temp.i <= thiso.rights.size()? You'd be excluding one less array item.

In general though, there really isn't anything to 'fix' persay if we don't even know how you store your array vars (this.orights? too vague) or what you're really trying to do. Apparently you want to change the array with '[' or / yet nothing is indicating any keypresses besides onKeyPressed() which you didn't utilize properly anyway. Wat?

I guess you want to increment your array [] selectors, so why not just increment temp.i and de-increment them on '[' & / keypresses?
