使用Windows“ cls”清除屏幕Java控制台应用程序中的命令 [英] Clear screen with Windows "cls" command in Java console application

问题描述

我正在开发一个游戏，该游戏涉及在每回合之后都要清除屏幕以提高可读性。唯一的问题是我无法使用基于Windows命令提示符的 cls命令，并且它不支持ANSI转义字符。我在下一页上使用了Dyndrilliac的解决方案，但它导致IOException：

I am working on a game that involves clearing the screen after each turn for readability. The only problem is I cannot use the Windows command prompt-based "cls" command and it does not support ANSI escape characters. I used Dyndrilliac's solution on the following page but it resulted in an IOException:

Java：清除控制台

用 cmd \C cls替换 cls只会打开一个新的命令提示符，已清除并关闭它而不访问当前控制台。如何使通过Windows命令提示符运行的Java程序访问命令提示符的参数并使用它们清除其输出？

Replacing "cls" with "cmd \C cls" only opened a new command prompt, cleared it, and closed it without accessing the current console. How do I make a Java program running through Windows Command Prompt access the command prompt's arguments and use them to clear its output?

推荐答案

new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();

我意识到这是一篇过时的文章，但是当我发现有以下问题的答案时我讨厌没关系，我懂了，否则就死了。希望它能对我有所帮助。

I realize this is an old post, but I hate when I find questions with responses of never mind i got it, or it just dies off. Hopefully it helps someone as it did for me.

请记住，它不能在Eclipse中运行，但可以在常规控制台中使用。如果您担心跨操作系统，请更进一步：

Keep in mind it won't work in eclipse, but will in the regular console. take it a step further with if you're worried about cross OS:

        final String os = System.getProperty("os.name");
        if (os.contains("Windows"))
            new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();
        else
            Runtime.getRuntime().exec("clear");
