Usage

From source file:de.tynne.benchmarksuite.Main.java

private static void checkNano(PrintStream ps) {
    List<Long> diffs = new ArrayList<>();

    nanoNullLoop(1000000, diffs);/*from  w ww.j a  v  a  2 s . c o  m*/
    diffs.clear();
    nanoNullLoop(1000000, diffs);

    LongSummaryStatistics statistics = diffs.stream().mapToLong(l -> l).summaryStatistics();

    ps.printf("min=%d, avg=%g, max=%d\n", statistics.getMin(), statistics.getAverage(), statistics.getMax());
