@Sirini,

I assumed you were using Java on Windows. My bad!

The best way to know what is hot and in demand in Java is to check Job Boards/Sites containing Java related Jobs. This will clearly tell you what are the latest trends in Java and what technologies are companies using in their project lately.

You can definitely install and use multiple versions of JDK on a single machine/OS. Just install the JDKs into different folders and then change the version when compiling your programs. If you want to test your code using different Java versions, you can create .bat files with various versions and then just execute one of those .bat files before using a particular version. For example, a .bat file for JDK 1.6 might look something like this:



You can name the file as jdk6.bat and then only execute this file before testing your program. You can do the same for other JDK versions.

Hi Johny,

You can either view the complete documentation with examples or contact Aspose.Cells support team for further help. If you're having any issue while using the component, please share the details.

Hi Tim, Johny,

I would like to share that Aspose.Cells for Java supports JDK 1.4 and above. It can also create and manipulate both XLS and XLSX files. You may also try the evaluation version at your end to see if it satisfies all of your requirements.

If you like "Head First..." series, they also offer "Head First Android Development". You may try that.

If you want to open multiple files at the same time and extract data from those files then you will have to try multithreading. In this way, you'll be able to read one file per thread. Please see the following two help topics on multithreading in Java:

Do all the components throw this exception? Looks like you either have a very large Excel file or low heap space allocated. As suggested earlier, please try to increase the heap space. Moreover, if you still find the issue with Aspose.Cells for Java, you may contact our support team via Aspose.Cells forum; we will have to investigate whether it is the size of the PDF file or particular structure which is causing the problem.

If I search algorithm on this site, I find most of the algorithm related discussions in General Computing forum. So, I suppose that's the forum where you should discuss this.

Hi Michael,

I got your point. In that case, I think you should post the query in Algorithm related forum. "Java in General" is not that specific. Well, wish you good luck in your endeavour.

By the way, I have also tweeted this so maybe some one good in algorithm come across and help you with this: https://twitter.com/#!/shahzad_latif/status/149861663842115586.

Hi Michael,

After reading your question, it looks like you want to process the Doc/Docx files in your Java applications. If you're planning to do it from scratch then I would say it's going to be very tough and complicated. However, you may want to try some Java based API to process the Word documents like Aspose.Words for Java. This is a commercial product though, you'll be able to process your documents quite easily with this component. You may try it at your end to see if it helps. If you need further assistance with this, please write back.

Hi,

Are you looking for a visual control to view and edit PDF files or for some API? For example, you can use an API to open a PDF file, fill its form fields, and then save the output file, however it will not provide any UI. So, one idea could be that you provide your own UI i.e. input fields to get values from your users and then use the API in your code to take those values from the input fields and then update the form fields inside the PDF file. If you think such an API can help in your scenario then you may try Aspose.Pdf.Kit for Java. However, if you want some visual control then may be someone else might suggest you something similar.

You might also want to have a look at Aspose.Cells for Java, which allows you to import data from a database to a worksheet. The process is as simple as the following three steps:

1. Query your data from the database
2. Put the data in ResultSet
3. Import the data from ResultSet to the worksheet

Please see if this might help in your scenario. Please also note that this component provides comprehensive documentation and support as well; it also provides a lot of other features to work with Excel files.
