classpath

[student4life]

Could someone show me how to echo classpath on windows DOS prompt? to
find path, one can just type 'path' but this does not work with
'classpath'. Thanks.

C:\>echo %classpath%

or

C:\>set classpath

I may be teaching my grandmother to suck eggs here, but bear in mind
that when you do this, you'll get the value of the CLASSPATH environment
variable...which if you did not explicitly set it somewhere will be
empty (unset). On any machine I routinely use this will always be empty,
because I never use the variable.

Typically you can expect Java applications to work with their own
classpaths, which often would be set in a startup script using "java"
options. That way they don't rely on a global or per-user CLASSPATH
single value which can be incorrect for any given app.

That is definitely good advice.

with 4NT, you can do
eset CLASSPATH

with MS command prompt you can do

echo %CLASSPATH%

That will echo the CLASSPATH variable. It won't necessarily show the
classpath for a particular Java run.

It was the CLASSPATH variable the original poster
asked how to display.

Perhaps.
