Tiny benchmarking framework for Java 7+

nanobench

This is a tiny benchmarking library for Java 8.

SYNOPSIS

Benchmark code(ListBenchmark.java): ``` import java.util.List; import java.util.ArrayList; import java.util.LinkedList;

public class ListBenchmark { // Benchmarking method must be started with 'bench'. public void benchArrayList() { List l = new ArrayList<>(); for (int i=0; i<1_000_000; ++i) { l.add(i); } }

public void benchLinkedList() {
    List<Integer> l = new LinkedList<>();
    for (int i=0; i<1_000_000; ++i) {
        l.add(i);
    }
}

} ```

Command line: ```

javac ListBenchmark.java java -jar nanobench.jar ListBenchmark
