node-jvm基于Node.js的Java虚拟机

node-jvm 实现了纯 Node.js 环境下的 Java 虚拟机。

示例：

java

public class Main {

    public static long fib(int n) {

        if (n <= 1) return n;

        return fib(n-1) + fib(n-2);

    }



    public static void main(String[] args) {

        if (args.length == 0) {

                System.out.print("help: java Main.class {Number}");

                return;

        }



        int N = Integer.parseInt(args[0]);

        long start = System.currentTimeMillis();            

        System.out.format("Fibonacci from 1 to %s:\n", N);

        for (int i = 1; i <= N; i++) {

            System.out.println(i + ": " + fib(i));

        }

        long stop = System.currentTimeMillis();

        System.out.println("time: " + (stop - start) + "ms");



        System.out.println("done.");

    }

}

node.js

var JVM = require("../../index");

var jvm = new JVM();

jvm.loadClassFile("./Main.class");

jvm.run([10]);
