Primitives class type

[Pho Tek]

I have a function that expects two things:
f (Class type, Object o) { ... }
Now I can pass in a boolean wrapper class like this:

// compiles fine
Boolean b = new Boolean(true);
f (Boolean.class, b);

But I can't pass in a boolean primitive:

// failed to compile
boolean b = true;
f (boolean.class, b);

Why?
I understand that class Class is a subclass of Object right?
So I tried java.lang.Boolean.TYPE to represent the type like this:
f (java.lang.Boolean.TYPE, b); // doesn't work either
But this works:
f (java.lang.Boolean.TYPE, new Boolean(b));
why oh why ?
Is java.lang.Boolean.TYPE = boolean.class ?

In java primative types boolean, int, long ,float etc. are not Objects and do not subclass object.
Thats why

Boolean b = new Boolean(true);
f (Boolean.class, b);

compiles, you pass an Object Boolean
and

boolean b = true;
f (boolean.class, b);

failes, boolean is a primative and NOT an Object
