这篇博文是用Windows Live Writer写的，看看效果 下面是以前写的程序：java中从控制台输入多行数据 按回车键输入空行结束 //试过几个插件，发现插入代码后都不能复制， 但是插入图片还是很方便的， 用wlw写博客好处是可以离线， 以后就用wlw写，然后发布草稿

这篇博文是用Windows Live Writer写的，看看效果

下面是以前写的程序：java中从控制台输入多行数据 按回车键输入空行结束

//试过几个插件，发现插入代码后都不能复制，

但是插入图片还是很方便的，

用wlw写博客好处是可以离线，

以后就用wlw写，然后发布草稿，再到CSDN插入代码后发表文章，只是写个博客要这么艰难吗！！！

Scanner scanner = new Scanner(System.in);

ArrayList ns = new ArrayList<>();

do {

String string = scanner.nextLine();

if (string.equals("")) {

break;

}

ns.add(Integer.valueOf(string));

} while (true);

System.out.println(ns);

输入：

4

5

6

7

输出：

[4, 5, 6, 7]

插入一个图片试试：

插入一个链接试试：

I have already tried getRootPane().setDefaultButton(myButton);, but only that does not seem to work.

而不是必须使用方法调用此按钮的代码
