How to write this method?

String getRotatedFullName(int shift). This method returns your name, rotated (with wrap-around), by 'shift' characters. Positive numbers rotate to the left, and negative numbers rotate to the right.

For example, for my name "Jim Jones", if I executed:
For example, for my name "Jim Jones", the following client code would behave as such:
System.out.println(j.getRotatedFullName(2));
System.out.println(j.getRotatedFullName(-5));
And I would expect to get the output:
m JonesJi
JonesJim
