Alternative implementation that also {{works with|Java|8+}} |

<lang java>import java.util.List; |

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" |
