[Edu-sig] looking for help with Jython...

[luby liao]

Jeffrey, try this:

1. change first line to

  public class Vehicle {

2. shell> javac Vehicle.java

3. shell> jython

[liao@zen tmp]$ jython
Jython 2.1 on java1.3.1 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> import Vehicle
>>> v = Vehicle(3,5,6)
>>> v
Vehicle@3f1179
>>>

cheers, Luby
