The following illustrates how to get the Number format working with a danish locale. import java.text.NumberFormat; import java.util.Currency; import java.util.Locale; public class TestLocale { public static void main(String args[]){ // Create a Locale for Danmark Locale DANMARK = new Locale("da","DK"); // get the currency instance for this locale. Currency krone = Currency.getInstance(DANMARK); // Get a Number format for the locale. NumberFormat krFormat = NumberFormat.getCurrencyInstance(DANMARK); // A symbol for the currency String symbol = krFormat.

Challenging Business requirements and the need for software development teams to remain agile and competitive while managing parallel development and releases requires a system which is adaptive to these demands. Our approach to SCM enables unlimited and adaptable process models, which are ideally suited for parallel, distributed, and agile software development. Using state of the Art technologies from various vendors to automate processes such as branching, merging, build, and release keeps you a click away from software delivery.

Someone just asked me this question today. And I thought might as well put it down for info. public TestReadFileFromJar() throws FileNotFoundException, IOException { InputStream is = getClass().getResource("txtData/states.properties"); read(is); } In the case above txtData is placed in the jar on the root. Remmember to add the path with the “/”

By using the command pattern you are seperating the operation from the invoking object. And just because of that it becomes easier to change the command without chagning the caller/s. This means that you could use Command pattern when you might have the following situation You want to parameterize objects to perform an action You want to specify, execute and queue requests at different times. Just to quickly start you need a command object, An interface will keep it easy going in this case, thus providing you with the option of extending other classes e.

Typically when implementing an interface you would have to implement all the methods that exist in that interface. A very good example is the MouseListener in the java Swing. When you need to implement more then one method where as typically you might be catching only one of them. Saying that you would also find a Mouse Adapter provided as well. Some of us use that often. And that is part of the Adapter pattern.
