Does java --classpath override CLASSPATH or append to it?
classpath, java
Solution
Looks like the -cp option overrides the CLASSPATH environment variable.
$ export CLASSPATH=Tests
$ java Printf
Team Name No. of Wins No. of Losses
Bobcats 0 0
Tigers 1 1
Lions 2 2
Cheetahs 3 3
Jackals 4 4
Leopards 5 5
Snow Leopards 6 6
Cougars 7 7
Mountain Lions 8 8
Bobcats 9 9
$ java -cp . Printf
Error: Could not find or load main class Printf
The CLASSPATH environment variable is still set to the folder Tests, however, when I use the `-cp` option it overrides it, and changes the classpath to `.`, the current directory, so my class file can no longer be found.
Problem
If I have ``` CLASSPATH=/blah;/foo ``` Then run ``` java -cp bar.jar com.yourcompany.SomeMain ``` Is the classpath now ``` bar.jar ``` OR is it ``` /blah;/foo;bar.jar ``` Basically does the command line switch override or augment the existing `CLASSPATH`?
