|
* <p> For a classic example, here is a task computing Fibonacci numbers: |
12 |
|
* |
13 |
< |
* <pre> |
14 |
< |
* class Fibonacci extends RecursiveTask<Integer> { |
13 |

* <pre> {@code |
14 |

* class Fibonacci extends RecursiveTask<Integer> { |
15 |
|
* final int n; |
16 |
|
* Fibonacci(int n) { this.n = n; } |
17 |
|
* Integer compute() { |
18 |
< |
* if (n <= 1) |
18 |
> |
* if (n <= 1) |
19 |
|
* return n; |
20 |
|
* Fibonacci f1 = new Fibonacci(n - 1); |
21 |
|
* f1.fork(); |
22 |
|
* Fibonacci f2 = new Fibonacci(n - 2); |
23 |
|
* return f2.compute() + f1.join(); |
24 |
|
* } |
