Q: Can the java [sic] code run without java virtual machine ?
Normally, no, but there are some compilers like GCJ (Gnu Compiler
for
J*va) that can run some Java code without a JVM.
When we instal the jdk [sic], does the java virtual machine setup
at
the same time?
It installs at the same time, in the form of the "java" command
(java.exe on Windows), so I guess you could say its set up at the
same time. There wouldn't be much point to the JDK without the JVM,
after all.
But simply installing the JDK doesn't *run* the JVM. That happens
when you (directly or indirectly) invoke the 'java' command.
What is the relationship between the fold jre and java virtual
machine ?
What do you mean by the "fold" JRE?
