使控制台等待用户输入关闭 [英] Make the console wait for a user input to close

问题描述

我有一个控制台应用程序，在执行任务后，必须向用户提供反馈，例如操作已完成或操作失败以及详细错误。

I have a console application that after performing its tasks, must give feedback to the user, such as "operation completed" or "operation failed" and the detailed error.

问题是，如果我只是让它运行，输出消息将被打印，但控制台将很快关闭，没有时间阅读消息。

The thing is, if I just "let it run", the output message will be printed but the console will close shortly afterwards, leaving no time to read the message.

据我记忆，在C ++中，每个控制台应用程序都将以按任意键退出或类似的结尾。在C＃中，我可以用

As far as I remember, in C++, every console application will end with a "press any key to exit" or something like that. In C# I can simulate this behavior with a

Console.ReadKey();

但我怎么能用Java做呢？我正在使用Scanner类，但鉴于输入是我的Scanner实例：

But how can I do it in Java? I'm using the Scanner class, but given that "input" is my instance of Scanner:

input.next()
System.exit(0);

任何关键都可以使用，除了退货，这在这里非常重要。任何指针？

"Any key" will work, except for return, which is quite a big deal here. Any pointers?

推荐答案

在Java中，这将是 System.in.read（）

In Java this would be System.in.read()
