Java中的多个命令提示符/控制台? [英] Multiple Command Prompts / Consoles in Java?

问题描述

也许是一个尴尬的问题，但我想知道是否有可能运行一个Java控制台应用程序，该应用程序以某种方式链接到多个命令提示符.

Maybe an awkward question but I am wondering whether it is possible to have one Java console application running which is linked somehow to more than one command promt.

我欣赏的是一个Java应用程序，它提供一个控制台来读取控制台输入，一个控制台来提供类型A的控制台输出，一个控制台来提供类型B的输出，等等.

What I admire is to have a Java application which provides one console for reading console input, one for providing console output of type A, one for providing output of type B and so forth.

对此有任何想法或评论吗?

Any ideas or comments on that?

我正在考虑类似..

System1.out.println(输出A");
System2.out.println(输出B");

我的特殊问题如下:

我必须通过控制台向用户提供大量输出，为了使其更具可读性并提供更多的结构概述，我想使用更多的控制台.

I have to provide lots of output to the user via the console and in order to make it more readable and to provide a more structures overview I would like to use more consoles.

推荐答案

不可能像您一样使用 System1.out.println("..."); 表明的;但是，系统可以使用"setOut(PrintStream out)"方法:

it is not possible to use System1.out.println("..."); like you've indicated; however, System has a "setOut(PrintStream out)" method that you could use:

try {
    PrintStream psA = new PrintStream("My_Output_A.log");
    PrintStream psB = new PrintStream("My_Output_B.log");

    System.setOut(psA);
    System.out.println("Message for A");

    System.setOut(psB);
    System.out.println("Message for B");

} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

上面的代码将消息打印到2个单独的文件中.
我认为这是您对应用程序所期望的.

The above code prints the messages to 2 separate files.
I think this is what you desired for your application.
