Java program terminates

[Meet Gaurav]

Hi

I have a java program that will run infinitely

In the code I added for(;;)

But when I start program in the unix machine using JAVA classname command from PUTTY session it’s started running. As soon as I close the Putty session the program is terminated.
We are expecting the java program to run even after closing the PUTTY session.

Whether the fork command will help ?

Please assist us

This has nothing to do with Java. Unix will terminate your shell and its subprocesses when you terminate the connection.
Use background execution (someCommand &), fg and bg, or the program called screen that can give you sessions in virtual terminals. Or run your Java code as a service (jWrapper, YAJSW).

Or nohup.
