Netbeans如何在Java中设置命令行参数

2022-01-21 00:00:00 arguments netbeans java

我正在尝试在 Windows 7 64 位上的 Netbeans 7.1 Java 项目中设置命令行参数.

I am trying to set command line arguments in a Netbeans 7.1 Java project on Windows 7 64 bit.

Netbeans 没有传递我给它的参数.

Netbeans is not passing the arguments I give it.

我转到 Project --> Properties --> Run --> 并在Arguments"旁边键入参数，但是参数不传递给程序.我如何通过它们?

I go to Project --> Properties --> Run --> and type the arguments next to "Arguments" however the arguments are not passed to the program. How do I pass them?

推荐答案

我猜你正在使用 Run |运行 File(或 shift-F6)而不是 Run |运行主项目.NetBeans 7.1 帮助文件(F1 是您的朋友！)Arguments 参数的状态:

I am guessing that you are running the file using Run | Run File (or shift-F6) rather than Run | Run Main Project. The NetBeans 7.1 help file (F1 is your friend!) states for the Arguments parameter:

添加参数以在应用程序执行期间传递给主类.请注意，参数不能传递给单个文件.

Add arguments to pass to the main class during application execution. Note that arguments cannot be passed to individual files.

我用一小段代码验证了这一点:

I verified this with a little snippet of code:

public class Junk
{
    public static void main(String[] args)
    {
        for (String s : args)
            System.out.println("arg -> " + s);
    }
}

我将 Run -> Arguments 设置为 x y z.当我自己运行文件时，我没有得到任何输出.当我运行项目时，输出是:

I set Run -> Arguments to x y z. When I ran the file by itself I got no output. When I ran the project the output was:

arg -> x
arg -> y
arg -> z
