Hi Experts,

   I am a software engineer with 10+ years of Microsoft programming experience.  VB, VC++, .NET, etc.  I am currently trying to teach myself Java and I have the hardest time making sense of the basics.

Here's what I think I know:

When I write code I create simple text files (.java).  Then I use something to compile it into bytecode files (.class) and then these bytecode files are interpreted at execution time by an OS specific Java Virtual Machine.


Here are my questions:

Am I correct in my above understanding?
What do I use to compile my .java files?
Is there a difference between JRE and JVM?
What is the difference between JDK and Java SDK?
Does the JDK contain both the compiler and the JVM?
When I download and install an IDE like Eclipse, does that also install the compiler and the JVM?
What is a Java Application Server?

Why does the Java community insist on having 15 different acronyms/names for the same piece of software and/or technology?  ¿


I know that these are a lot of questions but they should be rather simple for an expert.

Thanks!
