public class stringConcat

{

 public static void main(String args[])

 {

     String s1,s2,s3;

     DataInputStream d;

     try

     {

     System.out.println("Enter the First String");

     d=new DataInputStream(System.in);

     s1=(String)d.readLine();

     System.out.println("Enter the Second String");

     s2=(String)d.readLine();

     s3=s1.concat(s2);

     System.out.println("The new String is = "+s3);

     }

     catch(Exception e)

     {

         System.out.println(e.toString());

     }
