清除屏幕 [英] Clear the Screen

问题描述

我做了一些研究，尝试用java代码清除屏幕。


第一个选项是obv ：

system.out.print（" \\\\\\\\\\\\ n然后我听说这个方法：

System.out.print（（char）27 +" [2J"） ;


但是，除非ansi.sys，否则它不起作用。加载了很少的WinXP

用户有这个。


尝试解决这个问题的任何帮助。

干杯，

Dave

Hi,

I have done some research, trying to Clear The Screen in java code.

The first option was the obv:
system.out.print("\n\n\n\n\n\n\n\n\n\n\n\n");

then i heard about this method:
System.out.print((char)27 + "[2J");

However, it doen''t work unless "ansi.sys" is loaded and very few WinXP
user''s have this.

Any help appreciated in trying to solve this problem.

Cheers,
Dave

推荐答案

这是一种黑客攻击，但是这个怎么样：


Runtime.exec（" cls"）;


这使您的应用程序依赖于平台，但它看起来像你的/>
声明替代方案也是如此。

It''s kind of a hack, but what about this:

Runtime.exec("cls");

This makes your application platform-dependent, but it looks like your
stated alternative does this as well.

我之前看过这个问题 - 没有真正的解决方案。

当然，提供一个清晰的屏幕并不困难，甚至

基本的屏幕光标定位？

它会使文本模式java更有用。

Ive seen this question before- with no real solution.
Surely it wouldnt have been difficult to provide a clear screen, and even
basic screen cursor positioning?
It would make text-mode java alot more useful.
