If-Else strings

Question

Given a string and an integer value x, return a new string with the first x characters of the original string now at the end. Make sure there are enough characters before attempting to move them to the end of the string.

Sample Data : Data File: stringChopper.dat

apluscompsci 3
apluscompsci 5
apluscompsci 1
apluscompsci 2
apluscompsci 30
apluscompsci 4

Sample Output : (output needs to be exact)

uscompsciapl
compsciaplus
pluscompscia
luscompsciap
no can do
scompsciaplu

My code:

public class StringChopperRunner_Cavazos {
   public static void main(String[] args) throws IOException {
      Scanner fileIn = new Scanner(new File("stringChopper.dat"));

      while(fileIn.hasNext()) {
      System.out.println(StringChopper.chopper(fileIn.next(), fileIn.nextInt()));
      }
   }
}

class StringChopper { 
   public static String chopper(String word1, int index) {
      if(word1.length() < index - 1){
         return "no can do";
      }
      else {
         return word1;
      } 
   }
}

So my question is; How can I return the String with the index number indicated if it's less than that to make sure there are ENOUGH letters printed?

Use String#substring to find different portions of a String and then concatenate them together using the + operator.

if (word1.length() < index - 1){
    return "no can do";
} else {
    return word1.substring(index) + word1.substring(0, index);
}

Why does this question have three upvotes (currently) when it appears to me to be nothing more than an absolute basic homework question?
