One program for both Windows and Linux

Hi folks,

Java is new to me.

I'm looking for a programming language to create a program which can work on both Windows and Linux. Some folks suggest Java (not javascript). If it is the case please advise where shall I start?

Further detail will be posted if Java is the right way for me to go. TIA

Java indeed is platform independent; for a good start study the Sun Java Tutorial and if you really start expeirmenting don't forget to download the entire Sun Java API documentation.

Hi Jos,

Thanks for your advice and URL

A further question do I need requesting the Windows user to install Java framework for running the program thus created? Do all Windows have the said software running as basic? In the former case it is NOT so convenient.

Thanks

Yes, people do need to have a JRE (Java Runtime Environment) installed on their machine. You, the developer also need a JDK (Java Development Kit) installed. Those don't come with an OS distribution but users can implicitly install the JRE through the 'webstart' tool: it checks for the presence of an (up to date) JRE and installs one if not found on the target machine.

kind regards,

Jos

Hi Jos,

If I understand your advice correctly. When the user starts my program on Windows. If it is found No JDK available. It'll ask for permission to install it automatically. Please correct me if I'm wrong?

Thanks

Sort of: the user has nothing installed yet and s/he asks webstart to run your application; webstart checks if the user has a JRE available and installs it if it can't find any; then it downloads your application from the net and runs it; next time your user can do the same (a JRE won't be installed again) or s/he can install your application (and forget about webstart from then on).

kind regards,

Jos

His Jos,

Whether you meant Java Web Start ?

e.g. Web Start for Windows Vista
Free java web start for vista free Download - java web start for vista free Files

User needs to install this software first? Then use it to check the program. He/She only needs to do it once for ever.
