When you want to refer to the primitive type int as a class, use:
Integer.TYPE
the TYPE field is of type Class and is defined on all the primitive type
wrappers. For example:
public class A {
public static void main(String[] argv) throws Exception {
System.out.println(int.class);
System.out.println(Integer.TYPE);
}
}
both of these print "int". In fact, the int.class is substituted by my
compiler (javac 1.4.1 on a solaris 5.7 machine) in to the Integer.TYPE call.
So, you need to check the need to do something with the primitive type, and
instead of call Class.forName(<primitive type name>), you need to call the
appropriate wrapper.TYPE.
This is a pain, I agree, and it is a little sucky, I agree. However, it does
do the job :) Don't get me started on the use of primitives in Java, it's one
of my favourite rants about the language :)
