 import java.io.*;  
 public class EndsWith {  
      public static void main(String[] args) throws IOException  
      {  
           System.out.println("enter the ending string as your wish to check whether the string that is already defined is ends with this prefix string you entered or not");  
           checkToEndsWith();  
      }  
      public static void checkToEndsWith() throws IOException  
      {  
           String s1="Harry Porter";  
           BufferedReader b = new BufferedReader(new InputStreamReader(System.in));  
           String s2 = b.readLine();  
           if(s2.endsWith("Porter") || s2.endsWith("r") || s2.endsWith("e") || s2.endsWith("t") || s2.endsWith("r") || s2.endsWith("o") || s2.endsWith("p") || s2.endsWith("er") || s2.endsWith("ter") || s2.endsWith("rter") || s2.endsWith("orter"))  
           {  
                System.out.println("yes absolutely");  
           }  
           else  
           {  
                System.out.println("no");  
                System.out.println("try again");
