**Dear All,**

Please suggest some solution.

import java.io.*;
import java.util.Collections;
import java.util.List;
import java.util.ArrayList;
import java.util.Scanner;
import java.util.Timer;

public class Bin_search
{
public static void main(String args[])
{
Bin_search b=new Bin_search();

System.out.println("Enter the String");
Scanner input=new Scanner(System.in);
String msg=input.nextLine();
System.out.println(msg);

Message messageObject=new Message();
Time timeObject=new Time();

messageObject.simpleMessage(message);
timeObject.getTime();

System.out.println(msg + time);
}

}
