title: Find some values in a mongodb collection?
body: <p>Im trying to read a (mongo)userdatabase with java. On the tutorial page I saw how to read the whole collection. I can do something like that:</p>
  
  <pre><code>    DBCursor cursor = col.find();
      while (cursor.hasNext()) {
          System.out.println(cursor.next());
      }
  </code></pre>
  
  <p>Now if I have a collection with users := name, age, password (...) and whatever. Now I would like to find a name with a password. For example for a login process. Lets say I have two strings: String n and p. If there is a user.equals(n) and a password.equals(p) in the database then login user. How do I have to change my cursor? I saw some query examples on the mongodb java tutorial page, but duh I really dont get it...</p>
  
  <p>Any ideas? Thank you</p>
