Re: Help with -classpath and packages

Can anyone identify what I am doing wrong here-?

So I try this:

javac -classpath . TestCar.java

I get the error:
TestCar.java:8: cannot access Car
bad class file: .\Car.java
file does not contain class Car
Please remove or make sure it appears in the correct subdirectory of the classpath.

Well, the Car.java file should really be placed inside a directory called com/example/rentalcar
This is why it tells you to place it in the correct subdirectory,
or at least I think it is.
Usually you'd have a structure sort of like this:

projectdir/src/com/example/rentalcar/Car.java

projectdir/build/com/example/rentalcar/Car.class

When compiling from the src dir, just set the -d to ../build (backslash on windows, obviously).
If this doesn't work then I don't know,
I'd recommend you use NetBeans or Eclipse to do your projects though, it would simplify these tasks a lot.

Now if I try to use the fully qualified path to the package itself (I know this shouldn't work)

javac -classpath C:\Derek\java\com\example\rentalcar TestCar.java

I get the error:
TestCar.java:2: package com.example.rentalcar does not exist
import com.example.rentalcar.*;
TestCar.java:8: cannot access Car
bad class file: C:\Derek\java\com\example\rentalcar\Car.class
class file contains wrong class: com.example.rentalcar.Car

Obviously because there's no subdirectory com/example/rentalcar
.
