Answer 1

I would consider right method from StringUtils class from Apache Commons Lang: http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#right(java.lang.String,%20int)

It is safe. You will not get NullPointerException or StringIndexOutOfBoundsException.

Example usage:

StringUtils.right("abcdef", 3)
