If I want to instantiate a Date, I can use:
jclass cls = (*env)->FindClass(env, "java/util/Date");
jmethodID ctr = (*env)->GetMethodID(env, cls, "<init>", "()V");
jobject obj = (*env)->NewObject(env, cls, ctr);
But how do I instantiate an ArrayList<String>?

Generic types are instantiated to form parameterized types by providing actual type arguments that replace the formal type parameters. A class like LinkedList<E> is a generic type, that has a type parameter E .
A generic type is like a template. You cannot create instances of it unless you specify real types for its generic type parameters. To do this at run time, using reflection, requires the MakeGenericType method.
You can create an instance of a generic class without specifying the actual type argument. An object created in this manner is said to be of a raw type. The Object type is used for unspecified types in raw types.
In the same way. On VM level, there are no generics.
