Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;

public class displayHashTableData {

public static void main(String[] args) throws Exception {
Enumeration names;
String str;
double bal;
Hashtable<Integer,String> table = new Hashtable<Integer,String>();
table.put( new Integer(1111),"Selected");
table.put( new Integer(2222),"Not Selected");
table.put(new Integer(3333),"Not Selected");
table.put( new Integer(4444),"Selected");
System.out.println(" ");
System.out.print("Enter Ticket Number: ");
Scanner input=new Scanner(System.in);
int id = input.nextInt();
Set s =table.entrySet();
Iterator i=s.iterator();
while(i.hasNext())
{
Map.Entry map=(Map.Entry)i.next();
int key = (Integer)map.getKey();
String value=(String)map.getValue();
if(id==key){
System.out.println(value);
}
}
}
}

Hope that it will be helpful for you.
Thanks
