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]);
