How to create custom options when running Java from command line?

Question

Below is the example code where I want to pass custom options to run  compiled java code from command-line: 

java --output-dir "output_dir" --action Main

Can anyone tell me how to do this? 

Answer 1

If you want to run Java process, you can pass properties like below: 

-Dproperty=value

//you have to set system property value.

//For a String value with spaces, you need to enclose it with double quotation: 

java -Dmydir="some string" SomeClass
