Can you give me the methods for the start of this program that will??

// A method for finding the longest and shortest string
//and a method to split each word so i can see if it is a
// palindrome or not thanks for the help

I suppose you are allowed to use the String class' methods.
1. For longest & shortest word use length method of String.
2. To split use StringTokenizer class
3. For palindrome make use of the stack ds.
If you cannot use String methods you'll have to traverse the string maintaining a counter until you encounter a termination char like a space, comma, period or newline.
