javac command and -cp .

[Cyril Bil]

Hi guys.
I have this code:

public class Class1 implements Inter1 {}
public interface Inter1 {}

Is there a difference between :

javac my/path/to/java/Class1.java

and

javac -cp . my/path/to/java/Class1.java

Because I have the same result : compilation of the 2 classes

Thanks ;)

Yes, in the first case the class path is determined by the CLASSPATH environmental variable, or if it's not set, then the current directory is used for the class path.

The second case explicitly sets the class path to the current directory, overriding the CLASSPATH variable if it is set.
