Still working with the txt.file that I exported from my itp blog, I started by replacing all characters and non characters on the file with one single character, in this case /.
I wanted to visualize the patterns that a txt file can created.
The important and simple code I had to write:
String regex = ".";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(content);
String output = m.replaceAll("/");
