How can I pass a Class as parameter and return a generic collection in Java?

Question

I am designing a simple Data Access Object for my Java application. I have a few classes (records) that represents a single row in tables like User and Fr

Answer 1

You are pretty close.

public <T> LinkedList<T> getAllRecords(List<T> list) {
 ...
}

This is called a Generic Method.

You will want to specify a parameter like List<T>. Then, based upon the type of the list you pass in, Java will infer the generic type to return.

Edit:

Poly's answer is very good. It should be easy enough for you to do the following and not have to create a TypeReference class.

List<Fruit> fruit = myDataAccessObject.getAllRecrods(new LinkedList<Fruit>());
List<User> users = myDataAccessObject.getAllRecords(new LinkedList<User>());
