How To Instantiate a java.util.ArrayList with Generic Class Using Reflection? I am writing a method that sets java.util.List on target object. A target object and a generic

Answer 1

Generics is largely a compile time feature. What you are trying to do is the same as

}

Note: This could change with Types in Java 7.
