palindrome's?

[Dillinger4]

A palindrome is a text phrase the reads the same backwards as fowards. So i wrote quick little app to test for a palindrome but the only ones i can think of are mom, dad, redivider, and a couple of other's. Any one know of any more?

import java.io.*; 

   class palindrome{ 
      public static void main(String[] args){ 
    
   BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
 
   for(int i = 0; i <= 4; i++){     
     try{
        System.out.println("Enter a word to see if it is a   plaindrome:");    
        StringBuffer sb1 = new StringBuffer(buff.readLine());
        String s1 = new String(sb1);
        sb1.reverse();
     
      if(s1.equalsIgnoreCase(sb1.toString())){
          System.out.println(s1 + "  is a plaindrome  ");
      }else{
          System.out.println(s1 + "  is not a plain drome  ");  
           }
       System.out.println();
      }catch(Exception e ){System.err.println(e);} 
   }      
  }
 }
