Java SE(标准版)用于构建桌面应用程序。

Java ME (Micro Edition)适用于旧的移动设备。

Java EE(企业版)用于开发基于web的应用程序。

是的，您应该从Java SE开始。Java EE适用于web应用程序，Java ME适用于移动应用程序——两者都是基于SE构建的。

是的，从Java SE开始。你提到的所有任务都可以用它来处理。

Java ME是移动版，EE是企业版;这些是标准版的专业/扩展版本。

Java SE是用于桌面应用程序和简单的核心功能。Java EE用于桌面，但也用于web开发、网络和高级事物。

Developers use different editions of the Java platform to create Java programs that run on desktop computers, web browsers, web servers, mobile information devices (such as feature phones), and embedded devices (such as television set-top boxes). Java Platform, Standard Edition (Java SE): The Java platform for developing applications, which are stand-alone programs that run on desktops. Java SE is also used to develop applets, which are programs that run in web browsers. Java Platform, Enterprise Edition (Java EE): The Java platform for developing enterprise-oriented applications and servlets, which are server programs that conform to Java EE’s Servlet API. Java EE is built on top of Java SE. Java Platform, Micro Edition (Java ME): The Java platform for developing MIDlets, which are programs that run on mobile information devices, and Xlets, which are programs that run on embedded devices.

Java SE是构建Java EE的基础。

Java ME是用于移动设备的SE的一个子集。

因此，您应该为项目安装Java SE。
