Does java --classpath override CLASSPATH or append to it? -

this question has answer here:

• java -classpath option 4 answers

if have

classpath=/blah;/foo 

then run

java -cp bar.jar com.yourcompany.somemain 

is classpath now

bar.jar 

or it

/blah;/foo;bar.jar 

basically command line switch override or augment existing classpath?

looks -cp option overrides classpath environment variable.

the classpath environment variable still set folder tests, however, when use -cp option overrides it, , changes classpath ., current directory, class file can no longer found.
