That sounds a lot like homework so I am not surprised that you didn't get a response.Did you pass the course?

Did you find a solution for this ?You haven't received any help because the request looks a lot like a homework assignment and a lot of people are unwilling to do that.I have some suggestions: 1) You should make sure that you have a working copy of Java. Start at the Java Tutorial: http://docs.oracle.com/javase/tutorial/java/TOC.htmlIf you do not have a working Java on your machine, follow the link at the top right of that screen to 'Download JDK'. That is the set of programming tools you need to use to compile and run programs.The Installation Instructions will tell you everything you wish to know. I suggest that you use: http://notepad-plus-plus.org/ to type in programs.Good luck. Post more on the problem page for more help.

Did your main page has a same name as java?OrYou are running in cmd thenjavac A.java // this will compilerun like:::::java AAny other query then tell me..........

I believe the error should read "java.lang.NullPointerException"

This error simply means that whatever your application code is trying to get is not there- its a null. Its either out of range or does not exist at all.

You need OCR software (optical character recognition), though you didn't mention the format of the image format file that you have. You may consider using this freeware software to perform your OCR:http://download.cnet.com/Screen-Copy/3000-2094_4-10039293.html

You need to compile the .java file you have, and run the .class file that is produced.
Open up command prompt, go to your working directory. If your file was called Hello.java: In command prompt type "javac Hello.java". Now, in the working directory, you will see a new file, Hello.class. Run that file by "java Hello.class". Hope this helps!

there is no toolbox for sun java programming for it is not a gui language.
if u want java with toolbox,"visual java" is availale on the net, which is pretty much similar to visual basic,the only difference being the language used in the former is "java" and that which used in the latter is "basic".
