Java class to get random string of arbitrary lenght.
To get random string of 10 chars simply write:
RandomStringGenerator.getRandomString(10);
If you want to get random string with also special chars (e.g. punctuation chars) write:
RandomStringGenerator.getRandomString(10, true);
If you need to avoid some chars in the result, for example "<" and ">", write:
RandomStringGenerator.getRandomString(10, true, "<>");
