How to let user dynamically input parameter

[cake naiyou]

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".

You expect your users to run your program in eclipse?

Use Reader to read console input use or code Swing. Is this for an Eclipse enhancement requirement

[cake naiyou]

The application should be command prompt one. At present, the debugging and testing process will be done in Eclipse.

Ok then read user input on cmd prompt using reader

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

Alternately, allow the user to specify the input information in a command line parameter.

if it is a stand alone program (which uses public static void main(String[] args)) then you can use pass arguments at runtime.

public class Testing {
	 public static void main(String[] args)
	 {
		System.out.println(args[0]);
	 }
}

If you compile and run this class as

java Testing qwerty

then 'qwerty' will printed by

System.out.println(args[0]);

You can use a command-line argument, or the Scanner class is much easier to use than a Reader for keyboard input.
