/**

instance of type Foo.
* @param stuff the list of objects
* @return an object of type Foo
* @throws NoSuchFooException if there is no Foo in the list

Foo getLastFoo(List stuff) throws NoSuchFooException; |

Foo getLastFoo(List stuff) throws NoSuchFooException {
for (int i=stuff.size()-1; i>=0; i--) {
if (stuff.get(i) instanceof Foo) {
return (Foo) stuff.get(i);
}
}
throw new NoSuchFooException();
}

面试就一个题目？还是说coding方面就这一个？ |
