Hi,
I am new to this forum. When we say- java is platform independent and portable. But are there any specific differences in them- concept or say implementation wise.

Thanks
John

Do you know what a platform is?

That's the key here.

I'm sure you know what portable means.


I would bet that I've seen this question before.... if you're stuck, do a search then post back here what you find


When you do things right, people won't be sure you've done anything at all.

The JDK and JRE downloads are different for different operating systems, eg Windows, Linux. And there may be different versions for different chips, but most people nowadays use an i386, which works on Pentium, most AMDs (I think, not sure), etc.
 
It is sorta covered in the JavaRanch Style Guide.
