用java更新控制台窗口 [英] update the console window with java

问题描述

如何让java更新当前的控制台窗口，而不是去一个新的行（或附加新的内容到旧）。

例如，如果我想证明进度，我会输出 progress n 百分比。

显然我想要做的只是用当前百分比更新n。

<$ p

$

解决方案

$ p> public class Test {
public static void main（String [] args）throws InterruptedException {
for（int i = 0; i< 100; i ++）{
System.out.print（\rThinking ...+ i）;
System.out.flush（）;
Thread.sleep（100）;
}
}
}


所有控制台当然（一些IDE可能会斗争），但任何服从回车（\r）应该没问题。

How can i make java update the current console window instead of going onto a new line (or appending new content onto old).

As an example, if i wanted to demonstrate progress, i would output progress n where n would be the given percentage.

Obviously what i would want to do is simply update n with the current percentage. Any help would be appreciated.

解决方案

Something like this?

public class Test {   
    public static void main(String[] args) throws InterruptedException {
        for (int i = 0; i < 100; i++) {
            System.out.print("\rThinking... " + i);
            System.out.flush();
            Thread.sleep(100);
        }
    }
}

It's not guaranteed to work on all consoles of course (some IDEs may struggle), but any that obey "carriage return" (the "\r") should be okay.
