hi all
sorry for asking the following crazy question

JDK : development evironoment which is superset of all
JRE : set of runtime classes subset of JDK
JVM : intrepreter which depends of OS for conversion of byte code to HW understable code.subset of JRE.

why does sun provide JRE for each operating system..isnt JRE same for any OS? why not they just supply JVM for different problems.

please let me know..

HI
very sorry if you think that i am cross posting..

my doubt was just "IS JRE OS dependent?"

because what i understood is only JVM of JRE is OS dependent.

i want to make sure whether (JRE minus JVM) is OS dependent

so that only JVM can be provided for each OS keeping JRE the same for all OS?

am i wrong ?

sorry for not being clear.
please help me in this regard as i just started trying to understand java concepts.

regards
reddy
