import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Enumeration;
public class HashtableExample {
public static void main(String[] args) throws IOException {
Enumeration names, values;
String key;
int value;
BufferedReader br =new BufferedReader(new InputStreamReader(System.in));
// Creating a Hashtable
Hashtable<String, Integer> hashtable =
new Hashtable<String, Integer>();
// Adding Key and Value pairs to Hashtable
hashtable.put("Name1",444444);
hashtable.put("Name2",421421);
hashtable.put("Name3",456666);
String input="yes";
while(input.equalsIgnoreCase("Yes")){
System.out.println("Eneter the name");
String name= br.readLine();
names = hashtable.keys();
values=(Enumeration) hashtable.values();
while(values.hasMoreElements()) {
value = (int) values.nextElement();
key=(String) names.nextElement();
if(hashtable.get(value).equals(name)){
System.out.println(hashtable.get(key));
}else{
System.out.println("Number not found");
}
}
System.out.println("Do you want one more search");
