Using the system ClassLoader with Class.forName()

[learningjava]

Hi,

Part of my looks like this:

Class c = null;
c = Class.forName("Car");
//class Car is defined in this file itself
Object object = c.newInstance();
ArrayList arg = new ArrayList();
ArrayList types = new ArrayList();
arg.add (new String("description"));
types.add(String.class);
Object[] argValues=arg.toArray();
Class[] argtypes=(Class[])types.toArray(new Class[argValues.length]);
Method method;
method=c.getMethod("description", argtypes);

The whole code compiles fine.
But I get a runtime error which says there was a ClassNotFoundException.
I have changed the CLASSPATH to include the directory in which these
programs sit, but am still getting the errors.

Help, please! Why doesn't it find my class?

It looks like the 'Car' class is not fully qualified.....
So, add the package name to the "Car" string. Say this "file" is a piece of
code in package "org.foo".
Then do:

c = Class.forName("org.foo.Car");

Even better would be just this, if Car is in this file anyway:

c = Car.class;
