例子

爪哇

 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." );
    }
}

节点.js

 var JVM = require ( "node-jvm" ) ;
var jvm = new JVM ( ) ;
jvm . setLogLevel ( 7 ) ;
var entryPointClassName = jvm . loadJarFile ( "./Main.jar" ) ;
jvm . setEntryPointClassName ( entryPointClassName ) ;
jvm . on ( "exit" , function ( code ) {
    process . exit ( code ) ;
} ) ;
jvm . run ( [ 15 ] ) ;

构建java文件

cd examples/fibonacci; make

运行jvm

./fibonacci.js

干净的

make clean

输出
