If your class A that belongs to package P does refer to class B that
also belongs to package P, then, when you compile A.java in the
current directory P,

javac -classpath .. A.java

If you compile A.java in the current directory ../P, which is the root
directory of package P,

javac -classpath . A.java

In order to learn classpath setting for Java package, read the J2SE
basic documents for javac compiler.
