通过双击启动Java程序 [英] Launching a Java program via double click

问题描述

我有一个正在开发的Java程序.我想把它展示给我的女友，她对如何使用Java毫无头绪，并且使她很容易做到这一点.我知道第一步是从命令行将其编译为.class，但此后我一无所知.

I have a Java program that I have been working on. I would like to show it to my girlfriend, who would have no clue as to how to work with Java, and make it easy for her to do so. I understand the first step is to compile it to .class 's from the command line, but after that I am clueless.

我想了解如何在Windows和Mac OS上同时执行这两个操作(我和朋友一起在Mac上，但我的学校使用Windows计算机).

I would be interested in finding out how to do this both for Windows and Mac OS (I am on a Mac, along with my girlfriend, but my school uses Windows computers).

我去过Oracle并看过他们的演示，他们以.jnlp下载，这是朝正确方向迈出的一步吗?

I have been on Oracle and seen their demos, they download as .jnlp, is that a step in the right direction?

特别是，我正在寻找一种简单下载并启动的，不涉及终端的文件"(也许是带有命令行的文件?).

And specifically, I am looking for a "file" of some sort that is simply downloaded and launched, no terminal involved (maybe a file with a command line within?).

标题和引号通常表示启动Java桌面应用程序的两种不同方式.

The title and that quote typically represent two different ways to launch Java desktop apps.

1. 以.jnlp下载" 这是豪华"版本，称为 Java Web Start .对于开发人员(您)而言，这有点棘手，但对用户(您的朋友)而言则非常容易.
2. 通过双击启动Java程序" 通常与可执行Jar关联. (尽管JWS还支持双击"-但具有菜单和快捷方式.)

1. "download as .jnlp" That is the 'deluxe' version, known as Java Web Start. It is a little trickier for the developer (you) but very easy for the user (your friend).
2. "Launching a Java program via double click" is more commonly associated with an executable Jar. (Although JWS also supports the 'double click' - but with menus and shortcuts.)

这两种策略都可以在OS X，Windows或* nix上使用，但第一种策略具有JRE版本控制(确保最终用户具有JRE，并且足以运行代码)，并借助脚本以及许多其他钟声和口哨声."

Either strategy will work on OS X, Windows or *nix, but the first has JRE versioning (making sure the end user has a JRE, and it is recent enough to run the code) assisted by scripts, and many other 'bells and whistles'.

• JWS应用程序.通常是从用户计算机可以访问的网页或服务器上部署的，因此您的朋友浏览"到您发送给她的链接到在这里下载".
  • 当她到达您的网页时，deployJava.js将检查她的PC是否具有合适的最低Java版本来运行该应用程序.如果没有，她将指导您完成该过程.
  • 当确认JRE时(对于使用JRE更高版本的人来说是不可见的)，脚本将在网页中写入一个链接，默认情况下该链接是一个按钮.
    
  • JWS apps. typically deployed from a web page or server accessible to the user machine, so your friend 'surfs on over' to the link you sent her to 'Download here'.
    • The moment she arrives at your web page, the deployJava.js will check her PC has a suitable minimum version of Java to run the app. If not, she will be guided through a process to get it.
    • When the JRE is confirmed (which happens invisibly for those with a later JRE) the script writes a link in the web page that by default is a button.
      

    另一种较小的替代方法是 executable-jar .

    Another lesser alternative is an executable-jar.

    它在Jar中使用一个manifest.mf来指定主类.

    It uses a manifest.mf in the Jar that specifies the main class.

    虽然对最终用户的使用体验较小，但对开发人员来说也更简单-在有限的分发范围内，这种权衡可能会派上用场.

    While being a lesser experience for the end user, it is also simpler for the developer - a trade off that might come in handy for limited distribution.

    • 需要安装合适的JRE版本.
    • 用户可以从任何来源(USB，蓝牙，网站等)获取Jar，并将其保存在方便的机器上的任何位置.
    • 要启动它，用户双击 Jar.
    • Requires a suitable version JRE installed.
    • The user obtains the Jar from whatever source (USB, Bluetooth, web site etc.) and saves it anywhere on their machine that is convenient.
    • To launch it, the user double clicks the Jar.
