it is said, that as long as I live I will make mistakes. Since starting with programming I tend to the try and error princip. I always asked myself, if there is a possibibility to program without errors. Not every situation provides a sand box where experiments don´t risk any problems. Is there a chance for the highest efficiency level? I´m a beginner in Java - and in guitarplaying too. So, it is normal that not every idea fits with the no-error-criteria. But ...
The D chord should be without the open A string and F#dim should start in the
4.th fret, shouldn´t it?
Is it right? What makes jtab efficient? Learning what wrong and false is, should be theory. Wrong practice is always harmful. Right, why programming myself, when there are dozents of good-working programs ? It is the well known : money . Sure it is a free library because not everyone ( like me ) has the money for the top of the job programs. So, is it far away of thinking when expecting free source efficient and error-free?
