Hi all,

I have one application(for which i have installed separate JRE) that communicates with the help of the API given by the other application(which comes with its own JRE) to perform some task .But due to this dependance , we are forced to compile all our classes in other applications JVM (as opposite we wanted that only classes that are making use of their API should be compiled their and rest in our JVM) .

So is their any way so that we can get only those classes compiled which is required by other application's JVM , and rest in our JVM . ??

Thanks Herman

a It will print 1 because the statement is valid.
b It will print 2 because the statement is valid.
c It will throw an exception because a is undefined.
d It will throw an exception because the expression’s syntax is invalid.
