Java ArrayList<T> .convertall

Question

Does something like c# .convertall in Java exist?

Like

ArrayList<MyCalss> list = new ArrayList<MyClass>();
list.convertall(new Converter(...));

Answer 1

Depending on what exactly you mean by a converter, in Java 8 something like this could work:

ArrayList<MyClass> list = new ArrayList<MyClass>(someObjectsToFillTheList);
List<OtherClass> list2 = list.stream()
    .map(s -> new OtherClass(s)).collect(Collectors.toList());

In this case, the conversion is done by the constructor of OtherClass.
