有关Java编程的最重要的事情是什么？ [英] What are the most important things to learn about Java Programming?
问题描述
我对面向对象编程有很好的理解，但是自编程以来已经有一段时间了。我想再学一次。 Java编程最重要的部分是什么，这对学习很重要，所以我可以将自己标识为程序员。我以前在学习Swing时遇到了麻烦，但我放弃了，但是我想再次尝试学习它。成为一名优秀的程序员需要多少年？
I have a good understanding of object oriented programming but it's been a while since I programmed. I want to learn it again. What are the most important aspects of Java programming that are important to learn so I can identify myself as a programmer. I had trouble learning Swing before and I gave up but I want to try it again to learn it. How many years does it takes to be a good programmer?
推荐答案
自从你离开这门语言后，有些事情可能有所改变，这里有一些个人建议：
Some things may have changed since you left the language, here some personal proposals:
- Servlets和JSP，你应该把这个尘埃带到这个并包括一些EL（表达语言）
- 构建工具（ Maven 或 Ant ），现在大多数Java应用程序都是借助它们构建的。
- 任何Web框架（ Spring MVC ， Struts2 或JSF是不错的选择）
- IoC和ORM（ Spring 和 Hibernate 是不错的选择。）
- 拿一个期待 Apache Commons 并尽可能使用它们
- Servlets and JSP, you should take the dust off to this and include some EL (Expression Language)
- A build tool (Maven or Ant), most of Java application are now built with the help of them.
- Any Web Framework (Spring MVC, Struts2 or JSF are good choices)
- IoC and ORM (Spring and Hibernate are good choices)
- Take a look to Apache Commons and use them when possible
Java 5+的一些功能还包括：
Also some features from Java 5+ like:
