我有这段代码:

public static void main(String[] args) {
        Downoader down = new Downoader();
        Downoader down2 = new Downoader();
        down.downloadFromConstructedUrl("http:xxxxx", new File("./references/word.txt"), new File("./references/words.txt"));
        down2.downloadFromConstructedUrl("http:xxxx", new File("./references/word1.txt"), new File("./references/words1.txt"));
        System.exit(0);

    }

是否有可能运行这两种方法:down.downloadFromConstructedUrl()和down2.downloadFromConstructedUrl()同时？如果是这样,怎么样？
