Examples of java.util.concurrent.ForkJoinPool.execute()

java.util.concurrent.ForkJoinPool.execute()
Arranges for (asynchronous) execution of the given task. @param task the task @throws NullPointerException if the task is null @throws RejectedExecutionException if the task cannot bescheduled for execution

    MyRecursiveTask task=new MyRecursiveTask(array,0,array.length);
    
    /*
     * Send the task to the ForkJoinPool 
     */
    pool.execute(task);
    
    
    /*
     * Wait for the finalization of the task
     */
