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]);
