这是我的代码段：

public void joinRoom(String room) throws MulticasterJoinException {
  String statusCheck = this.transmit("room", "join", room + "," + this.groupMax + "," + this.uniqueID);

  if (statusCheck != "success") {
    throw new MulticasterJoinException(statusCheck, this.PAppletRef);
  }
}

但是由于某种原因，if (statusCheck !="success")正在返回false，从而抛出MulticasterJoinException。
