Tell me about the Java Collections framework, what are its main interfaces. OK, what are the main differences between the Set and List interfaces? What do you give up if you go from a List to a Set, and what do you get in exchange for this if you go from a List to a Set? How would you go about guessing the order of an iteration() of HashSet if I told you I was going to insert the strings "first", "second", "third", "forth", and "fifth"?

Write a Program to find out Whether a given String can be a Palindrome i.e. we need to see for the palindrome after rearranging the words in that string.
example: lets say we have a string "aabbccd" so it can be a palindrome after rearranging the words "abcdcba".
For this I need to find out the optimal solution.
