In my current program, the input information is hard coded. For instance

final String titleFieldName = "title1";

If I want to change title1 to title2, I have to modify the source code and click "run Java application" in Eclipse. How can I change the program to allow the user dynamically input the parameter after clcking "run Java application".

How does Eclipse get involved here? What if the program is not in Eclipse?
For a normal program with a GUI interface, the user can enter a String via a text field and then that String can be copied to a local, non-final variable.

It should be command prompt application. Thanks.
