[project topics]

Code:

import java.io.*;
class Dem20
{
   public static void main(String args[])throws IOException
{
     BufferedReader b=new BufferedReader(new InputStreamReader(System.in));
     int i,n=0;
    String s1;
try
        {
     System.out.println("enter the size of array:");

       n=Integer.parseInt(b.readLine());
          String s=new String[n];
           System.out.println("enter the string:");
               for(i=0;i<n;i++)
               {
                       s[i]=b.readLine();
                }
            for(i=0;i<n;i++)
               {
               StringBuffer sb=new StringBuffer(s[i]) ;
                s1=new String(sb.reverse());
                   if(s[i].equals(s1))
                  {
                    System.out.println("String is"+s[i]+""+"palindrome");
                  }
                 else
                 {
                    System.out.println("String is"+s[i]+""+"not palindrome");
                  }
            }

       }
     catch(Exception e)
      {
         System.out.println(e);
       }
  }
}

OUTPUT
E:\3msc\java\meenu>java Dem20
enter the size of array:
3
enter the string:
aba
joby
jiss
String is aba palindrome
String is joby not palindrome
String is jiss snot palindrome
