« export to excel but in new page | Java learning videos » Comparision between C# and JAVA by Vahid 25. January 2009 15:30 here is a quick comparision between microsoft c# (.net) and java Concept C# Java Notes Virtual machine CLR JVM CLR is not quite the same as JVM concept, but very similar. Namespace namespace/ using package/ imports C# allows multiple namespaces in a file, Java does not. Attributes [attribute] @annotation C# 1.0, Java 1.5 Base class base super abstract objects abstract class abstract class abstract methods abstract abstract sealed objects sealed final In both cases, sealing is discouraged. sealed methods sealed final replacement methods new keyword not supported Effectively ignores the base method. constants const / readonly final static Enum’s enum keyword enum keyword C# 1.0, Java 1.5 virtual functions explicit virtual always virtual This is one of the gotcha’s when working between the two languages override intention override @Override (though members override by default) Causes compiler error if method is not actually overriding a base method. Class/Type representation of simple types Map 1:1 with the simple type keywords. Behave different to simple type keywords. C# seems more natural than Java in it’s behavior Getters/Setters get/set keywords, behave like properties Explicit get/set methods Again, C# seems more natural with this. Events Typically via delegates Typically via interfaces Reference equivalence Object. ReferenceEquals() == Another C# vs Java gotcha. Value equivalence == or Object.Equals() object.equals(), == for value types Java’s choice of using == for reference equals adds to the need to distinguish between objects and value types. Object introspection Object.GetType() object.class Very similar Exceptions thrown by method implicit throws keyword Actually liking Java’s philosophy here, albeit taking some getting used to. Stack scoping using keyword, or try/finally keywords try/finally keywords ‘using’ keyword is syntax sugar that calls IDisposable.Dispose() method at end of block. Simple synchronization lock keyword synchronized keyword ‘synchronized’ can also be used on a method. Generics class<type> class<type> C# 2.0. Java 1.5. C# has a cleaner implementation and discovery of generics in reflection. In Java, class and class<type> cannot co-exist. class becomes synonymous to class. Output parameters out, ref Not allowed Not a huge loss in Java, there are simple workarounds. Switch fall-through Not allowed Allowed iteration foreach(type x in y) for (type x : y) C# 1.0. Java 1.5. Lambda/Closures => (future) C# 3.0. Java 1.7 (maybe) .Net | JAVA | Technical ...

« Why Grandma should not do sky diving | Comparision between C# and JAVA » export to excel but in new page by Vahid 20. January 2009 05:42 in the last sub system which we were working on, there was requirement to export the result of a query which is from oracle database and is displayed in an asp.net data grid into excel file. but the component we are using for export to excel functionality gets the collection as input parameter and export the data to excel file and write the excel file into response object of the asp.net. this means once the functionality is invoked, a dialog box will be displayed asking Open the file, save the file of cancel the operation. no issue with save and cancel. but when they clicked on the open it opens the excel file in the same browser window where they were viewing the page and they close the window once they were through with viewing the excel file. this means they close the application. ...

As such, it is not strictly a method for building “web services.” The terms “representational state transfer” and “REST” were introduced in 2000 in the doctoral dissertation of Roy Fielding,one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification. ...
