CSCI 1302                        HW 4                               Summer 2008

     Compiling and running on the Unix command line with Java packages


Part 1, step 0: just compile A and B as given.

From within H4:
 javac pkg1/A.java
 javac pkg1/B.java
or
 javac pkg1/B.java

From the parent directory of H4:
  to compile B successfully, need to change the name of the
  package to H4.pkg1 in A.java and B.java, then:
 javac H4/pkg1/B.java


To avoid changing the package names, do compile and run from H4.


Part 1, step 7: include pkg1. with A in the declaration:
 public class D extends pkg1.A {

To compile D,javac pkg2/D.java works, but javac pkg2.D.java does not.

Having compiled pkg2/D.java, either
 java pkg2/D or java pkg2.D works to run D.


Part 2, step 6: the declarations for client2.java need to import pkg1,
like this:
 package pkg3;
 import pkg1.*;
