Java控制台程序 [英] Java console program

问题描述

我想知道如何制作Java控制台程序。我使用Eclipse作为IDE。寻找与C＃版本的控制台程序类似的东西。

I was wondering how to make a Java console program. I use Eclipse as IDE. Looking for something similar to C#'s version of a console program.

尝试过Google，但只发现导出到JAR并从命令行解决方案执行。我希望在控制台窗口中进行编译和直接测试。

Tried Google but only found export to JAR and execute from command line solutions. I would prefer to compile and directly test in a console window.

预先感谢

推荐答案

/*
 * put this in a file named CommandLineExample.java
 *
 */

class CommandLineExample
{
    public static void main ( String [] arguments )
    {
        System.out.println("Hello, world");
    }
}

在命令行中键入以下内容进行编译：

type the following from the command line to compile it:

$ javac CommandLineExample.java

然后您可以从命令行像这样运行它：

then you can run it from the command line like this:

$ java CommandLineExample
