Alternative implementation that also {{works with|Java|8+}}
<lang java>import java.util.List;
import java.util.function.IntSupplier;
import java.util.stream.IntStream;
import static java.util.stream.Collectors.toList;
public interface ValueCapture {
public static void main(String... arguments) {
List<IntSupplier> closures = IntStream.rangeClosed(0, 10)
.<IntSupplier>mapToObj(i -> () -> i * i)
.collect(toList())
;
IntSupplier closure = closures.get(3);
System.out.println(closure.getAsInt()); // prints "9"
}
}</lang>
