String question

[omar bili]

Hi
i need the function that can give me all the possibilities
that a number of letter in a String can produce, ex:
abc
output =>
abc
acb
bca
bac
cab
cba

the number of possibilities is the factorial of abc.length() =>
3! = 6
Thanks.

Well there isn't an existing method (Terminology Tip: there are no functions in Java) in the API to do this, so you have to write it yourself.

Not entirely true. Eg the length of the string "aaa" is 3 yet the number of combinations is 1.
