Jbuilder is just a development environment. To use it, you must give it a valid java runtime environment. That environment contains the entire Java language, so you don't need to install something else.\n\nShort of specifying what the actual problem is, the only thing I can say is that you are not using the Scanner and JOptionDialog properly.\n\n(Scanner does not seem to be an actual class from the original Java API. Did you mean something else?\n\nEdit: The Scanner class is a new class in JRE 5.0 - Just ensure JBuilder is using JRE 5.0)

Have you tried any IDE for developing interfaces? For J2EE development you can use something like WSAD (WebSphere Application Developer) made by IBM. There are many different products available.

You want to use it without a license? David Swofford won't be too happy about it. \nBesides, these beta versions are still not debugged.

microsoft doesn't come with java that most people use.  go to sun java and download it after installing it, it should work.

Go to microsoft.com and search for "debugger."\n There's several--- a script debugger, VB debugger, etc. Pick the one that's designed for the debugging you want to do, although the Script Debugger will let you debug lots of different web technologies. Instructions for install and use are on the site, too.

So some searches on Yahoo for java, VB and oracle.\nThis should give you some information, and ideas on what they are, and how to use them.

For the starters you should use a simple notepad or textpad or edit plus as editors. Installing and using a fancy IDE will take the focus off learning and you will end up struggling with features of IDE. Once you have grasped the concepts, you can switch to Eclipse, or even download NetBeans from sun.java.com\n\nTo save your file as java, just put the file name in double quotes when saving e.g. "MyClass.java", or select '*.*' under file types when saving java file from notepad or any such basic editor.\n\nHTH.

In short ,\nJDK for creating your own programs and runnig them, testing them\n\nJDK used by everyone to run java programs like applets and other things.\n\nboth JDK abd JRE provide the same JVM (for a particular version, on a particular platform)\n\n\n\n-------------------\nJDK is the development kit that bundles java compiler and java virtual machine (JVM)\n\nyou need java compiler to make a .java file to .class file\n\nthe .class file will run in a jvm.\n---------------------------------\n\nyou will also get just jre that is java runtime environment\nwhere you can only run .class file \n(as opposed to making a class file from java file  using JDK)\n\nthe JRE primarily bundles JVM so that you can use any class file to run...\n\n\nthe JVM( virtual machine ) translates the .class file to machine instructions in its container...\n---------------------------------------

i use microsoft visual C++ in the visual studio suite. Sometimes Microsoft has its own proprietary functions that will not work when not compiled with visual studio though, so you would have to watch out for that.\non linux, i just use the native eclipse with c/c++ plugin. eclipse has a lot of features though so it might be a bit confusing if u're not used to it.
