How to have Java method return generic list of any type?

Question

I would like to write a method that would return a java.util.List of any type without the need to typecast anything:

List

        

Answer 1

You can simply cast to List and then check if every element can be casted to T.

public  List asList(final Class clazz) {
    List values = (List) this.value;
    values.forEach(clazz::cast);
    return values;
}
