访问另一个类中的可观察列表

Question

Let's say I have a class:

public class FutureTask extends Task<ObservableList<Future>> {
   @Override protected ObservableList<Future> call() throws Exception
     ObservableList<Future> futureList = FXCollections.ObservableArrayList();
     ....
     /// a bunch of things here to build and manipulate the list
     ....
  return futureList;

If I had another class

public class {
// What would I enter here to get a variable x so:
x = futureList?

I tried doing ObservableList<Future> x = FutureTask.call() but I keep getting a static reference error.

FutureTask is only used once in the code, so would I have to declare it static ?

Answer 1

ObservableList<Future> x = new FutureTask().call();

会做魔术。
