> I want to know why sometimes we need -d option when executing java class from comand prompt? Is there any other way to handle it? I have a java class which I need to run from command prompt as:
> C:/>java -DVicuna=c:\vicuna DisplayInfo
> If I ommit -DVicuna, the application does not run. Why? Is there any other way?
When you use -D, you are basically setting a system property, in your case setting a property by the name Vicuna with a value c:\vicuna.
The reason your program does not work when you omit -D is because the property being looked for by your program is not found.
