jshell中的多行粘贴 [英] Multiline paste in jshell

问题描述

我正在尝试使用jshell，但找不到粘贴多行表达式的选项。甚至可以在jshell中粘贴多行。类似于scala提供的粘贴模式。

I was trying out jshell and couldn't find option to paste multiple line expressions. Is it even possible to paste multiple lines in jshell. Similar to what scala offers with paste mode.

推荐答案

所以如果你有这样的代码：

So if you have code like this:

 int c = 2;
 int j = 4;
 int x = 5; 

复制并粘贴到jshell中，只处理前两个语句。

Copy and paste into jshell, only the first two statements are processed.

但如果你有这样的代码：

But if you have code like this:

  int c = 2; int j = 4; int x = 5;

并粘贴到jshell：

And paste into jshell:

jshell> int c = 2; int j = 4; int x = 5;
        c ==> 2
        j ==> 4
        x ==> 5 

更多这样的代码行：

HashMap<Integer, Integer> map2 = new HashMap<>(); for (int i = 0; i < 15; ++i) { map2.put(i, i);map2.put(i, i); } System.out.println(map2);

实际上会有效。

为什么？我不知道。

我知道复制/粘贴的唯一方法是通过（在jshell中输入）：

The only way I know that copy/paste will work is via (type it in jshell) :

/ edit

/edit

你可以粘贴为你想要的很多。

and you can paste as much as you want.
