如何将我的 Java 程序转换为 .exe 文件？

我有一个查询，我开发了下面的 java 计算器，为了执行我可以在 eclipse 上运行这个应用程序，但我想创建它的可执行文件，以便我可以通过映射快捷方式与 exe 来创建它的快捷方式文件，当我点击图标时，计算器应用程序被执行，下面是 java 代码，请告知..

由于它是基于 Swing 的桌面应用程序，部署它的一个好方法是直接从使用Java Web Start的链接。

Java Web Start (JWS) 是 Oracle Corporation 的技术，用于直接从网络或 Internet 链接启动富客户端（Swing、AWT、SWT）桌面应用程序。它为支持 Java 的平台提供“一键式”安装。

JWS 提供了许多吸引人的功能，包括但不限于启动屏幕、桌面集成、1文件关联、自动更新（包括延迟下载和更新的编程控制）、按平台、体系结构或 Java 版本划分本地和其他资源下载，运行时环境配置（最低 J2SE 版本、运行时选项、RAM 等），使用扩展轻松管理公共资源。

当然，JWS 旨在用于部署应用程序。到 Windows、OS X 和 *nix，而不仅仅是 Windows（对于 a .exe）。

  1. 可以为应用程序指定桌面快捷方式和菜单项（带有图标）。在后来的 JRE 中，还有IntegrationService. 用于安装快捷方式（和文件关联）的 API。

您可以在 Eclipse 中创建一个可运行的 jar（在 File/Export 下）或使用诸如launch4j 之类的工具

Java 不是您通常转换为 exe 文件的东西，您必须将其转换为“JAR”或 java 存档，这实际上比分发 exe 文件更好，因为它不限制它可以运行的平台上。

在 Eclipse 中实际上很容易做到。

我不知道您使用的是哪个版本的 Eclipse，但您可以右键单击该项目并查找“导出”选项。然后您可以在其中一个选项中选择“JAR 文件”。

祝好运并玩得开心点！
