Again, not really. The Java source code is actually compiled to a binary
form which is called "Java Byte Code". This byte code is similar in
nature to a normal processor's instruction set. 
I guess you could say that the JVM "inteprets" the byte code. But I
think of it more like the JVM includes a byte code emulator (like the
old 1401 emulator). But, from what I can tell,the Java byte code doesn't
match the zSeries instruction set very well. So it is relatively
inefficient.
