I can understand cmd but not cmd /c. I was trying to invoke a java program from the current for which I use Runtime.getRuntime().exec("cmd /C java helloworld"); There arises my doubt.

The part you should be interested in is the /? part, which should solve most other questions you have with the tool.

For example, /V:ON would allow !var! to expand the variable var at execution time. The var syntax expands variables at input time, which is quite a different thing when inside of a FOR loop. /V:OFF Disable delayed environment expansion.

/C Carries out the command specified by the string and then terminates.

You can get all the cmd command line switches by typing cmd /?.
