How to compare the value of a specied attribute to a string

Question

I am looking for an example of how to compare the value of an attribute to a string. (I think)
I have been trying to:
if (attrs.get("title")== "Vampire") -- you already know this did not work.
How can I check to see if the title="Vampire"?
The code below will get me the title of admin (which should be Vampire)
import javax.naming.Context;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.DirContext;
import javax.naming.directory.Attributes;
import javax.naming.NamingException;
import java.util.Hashtable;
class Giles {                  
public static void main(String[] args) {
          Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://192.168.1.55:389/o=sunnydale");
     try {                                                                     
     DirContext ctx = new InitialDirContext(env);
     Attributes attrs = ctx.getAttributes("cn=admin");
     System.out.println("Title: " + attrs.get("title").get());
     ctx.close();
     } catch (NamingException e) {                                     
     System.err.println("Problem getting attribute: " + e);
Thank you!!

I guess, you are looking for searching for attributes of an user object.
Here is the sample code to list all the attributes of an 'user' objectclass.
Tell me if it helps or not.
import java.util.Hashtable;
import javax.naming.ldap.*;
import javax.naming.directory.*;
import javax.naming.*;
public class GetAttributes
     public static void main (String[] args)
          Hashtable env = new Hashtable();
          //Must use either the userPrincipalName or samAccountName,
          //Cannot use the distinguished name
          String adminName = "cn=abcd,cn=Users,dc=ssotest,dc=com";
          String adminPassword = "DEF1234";
          String ldapURL = "ldap://pni3w067:389";
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.SECURITY_AUTHENTICATION,"simple");
          env.put(Context.SECURITY_PRINCIPAL,adminName);
          env.put(Context.SECURITY_CREDENTIALS,adminPassword);
          //connect to my domain controller
          env.put(Context.PROVIDER_URL,ldapURL);
          try {
               // Create the initial directory context
               DirContext ctx = new InitialLdapContext(env,null);
               // Create the search controls
               SearchControls searchCtls = new SearchControls();
               //Specify the search scope
               searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);
               //specify the LDAP search filter
               String searchFilter = "(&(objectClass=user))";
               //Specify the Base for the search
               //cn=policygroup,ou=policyusers,ou=ssoanay,;
               //String searchBase = "ou=policyusers,ou=ssoanay,dc=ssotest,dc=com";
               String searchBase = "cn=abcd,cn=users,dc=ssotest,dc=com";
               //initialize counter to total the results
               int totalResults = 0;
               // Search for objects using the filter
               NamingEnumeration answer = ctx.search(searchBase, searchFilter, searchCtls);
               //Loop through the search results
               while (answer.hasMoreElements()) {
                    SearchResult sr = (SearchResult)answer.next();
                    totalResults++;
                    System.out.println("\nName of Object : " + sr.getName());
                    // Print out some of the attributes, catch the exception if the attributes have no values
                    Attributes attrs = sr.getAttributes();
                    //System.out.println("6");
                    if (attrs != null) {
                         try {
                              /*NamingEnumeration enum = attrs.getIDs();
                              while(enum.hasMore()) {
                                   System.out.println("IDs:"+enum.next().toString());
                              NamingEnumeration enum2 = attrs.getAll();
                              while(enum2.hasMore()) {
                                   System.out.println("Attribute - "+enum2.next().toString());
                         catch (Exception e)     {
                              System.out.println("Exception:" +e.getMessage());
                    else {
                         System.out.println("attribute is null");
               System.out.println("Total results: " + totalResults);
               ctx.close();
          catch (NamingException e) {
                    System.err.println("Problem searching directory: " + e);
     //return 0;
