How can I select the last 2 chars of a string

Question

Hello all,
I am trying to select the last 2 characters of a string to match them to another string. This is for a Poem generator that contains 20 or so words and I have to pick 2 words at random, them look at the last 2 characters to see if they match in each string. Say "Plain" and "Rain" would match because they both have "in" at the end. The length of each word could vary. I don't want this doing for me just what Method should I be looking at.
Thanks.

hi,
try this:
public class StringTest {
     public static void main(String args[]) {
          StringTest obj = new StringTest();
          obj.same();
     void same() {
          String rain = new String("Rain");
          String plain = new String("Plain");
          int rainLength = rain.length();
          int plainLength = plain.length();
          if(rain.substring(rainLength-2).equals(plain.substring(plainLength-2))) {
               System.out.println("same");
          else {
               System.out.println("different");
}you can use the length method to get the length of a string and then use the substring method, passing it length-2, so get the last 2 chars.
