Return Values from Java to Unix

How do I return data back from a Java program to a Unix script?

Answer:
The simplest, and perhaps best, way to do this is to print the values to standard output and parse them in the script. It is normal for shell scripts to use the printed output of other programs in one way or another.

Another alternative is to write the values to a file. Other forms of interprocess communication can be used, but provide overly complicated solutions for the simple case of returning values to a script.
