Raymond,
You can get the type of T if you have a parameterized field of a generic
type. Some thing like this,
import java.lang.reflect.Field;
import java.lang.reflect.ParameterizedType;
public class Test<T> {
private Test<String> myField;
/**
* @param args
*/
public static void main(String[] args) throws Exception {
Field field = Test.class.getDeclaredField("myField");
ParameterizedType parameterizedType =
(ParameterizedType)field.getGenericType();
System.err.println(parameterizedType.getActualTypeArguments()[0]);
}
}

1) No. T is erasable.
2) If myClass is a class or generic type, you should be able to "new
Test<myClass>".
On the other hand, if myClass is a pointer/variable, no you can't
"new Test<myClass>"
