jLine requires a .dll on windows making it not OS agnostic. If this existed in java itself, this problem would not be a problem because java internal dll are signed by java and can be included without issues.
But then, why doesn't java have this?

Hi,
You might find an open source package like JLine would have the full featured terminal support you are looking for. http://jline.sourceforge.net/ Roger

Unfortunately, that class does not include useful functionality for java programs to work on the console and output formatted text. The feature I miss the most is knowing how many columns I have to type into in order to deliver an easier to read formatted output while avoiding line wraps that are not coded in. There are other things I miss like having multi-line progress bars (so far I can do single line if it is the last line by using "\r" and re-writing the line). Other times, it is more user friendly to wait for any key press instead of specifically waiting for "Enter" which will also add more lines to the console. I did some search and found nothing about this. Why hasn't this been implemented for java code?
