回答1:
The most straight forward way is to create an RMI method call.
It's built into java from the beginning, reasonably simple and lightweight.
回答2:
The two programs run in separate processes. You will need to create an interface between the processes (or as Matthew put it: implement inter-process communication). There are millions of ways to achieve this, just to name a few:
- Create a file-based interface (Test will write into a file and JLabel will read that file)
- Create a TCP/IP connection between the two
- Create a HTTP connection between the two (JLabel may run a glassfish thread or something like that)
- Create a JMS connection
- Create an RMI method call
- Create a Webservice (again with JLabel running glassfish)
- Many more...
