the topic name is not same in publish and subscribe?

[qian0205]

hi, i am confused,
The RosTest code in the tests package:
the subecribe code: bridge.subscribe(SubscriptionRequestMsg.generate("/ros_to_java"), the topic name is /ros_to_java,
but in the publisher, Publisher pub = new Publisher("/java_to_ros", "std_msgs/String", bridge); the topic name is /java_to_ros. is this case right?

Thanks
