Java call the Scala' Object elements Error

Question

My Code as below:

 public static boolean createTopic(String topicname, String zkUrl, int sessionTimeout, int connectTimeout, int partitions, int replicationFactor){
    boolean result = false;
    ZkUtils zkUtil = ZkUtils.apply(zkUrl, connectTimeout, sessionTimeout, JaasUtils.isZkSecurityEnabled());
    RackAwareMode rackAwareMode = RackAwareMode.Enforced;

    if(AdminUtils.topicExists(zkUtil, topicname)){
        return true;
    }
    else{
        AdminUtils.createTopic(zkUtil,topicname,partitions,replicationFactor, null, null);

    }
    return result;
}

and the Scala code as below

object RackAwareMode {
   case object Disabled extends RackAwareMode
   case object Enforced extends RackAwareMode
   case object Safe extends RackAwareMode
}
sealed trait RackAwareMode

The Error arised at the line below: RackAwareMode rackAwareMode = RackAwareMode.Enforced;

Any ideas for me?

The Error is "expression expected" – zhangkuantian Sep 21 '16 at 09:56 — zhangkuantian, Sep 21 '16 at 09:56

Use RackAwareMode.Enforced$.MODULE$instead. The reason is how Scala generate inner classes.
