Server procces the commands

I currently have a server that receives information from the client. However in my code I have a if statement for every command I receive. Can this be done better?

    Public class receiveRepository implements Runnable {


    @Override
    public void run() {
        while (connected) {
           // receive stuff
           if(receive.equals("something"){
               //do something
          }
           else if(receive.equals("something else")){
                //do something else
             }
         //ect
        }
    }

}
