用VB.net编写网页游戏辅助工具，应该学习哪一个方面的知识？2.语法,,数据类型
3.能编一些小程序..
4.类集
5.JDBC...
6.事件驱动
7.网络.
8.hibernate
9.spring
10.j2ee
编号错了..呵呵...算了不管了..
其实JAVA嘛...很简单...对一个有C基础的人来说
没C基础的人学起来也很简单....
最重要的是要有一个类与对象的概念....
class __Main_Test
{
public static void main(String[] args) throws Exception
{
//最简单的程序的结构
}
}
【vb.net基本知识的简单介绍】__Main_Test就是一个类...
而对象呢....对象就是一个类的实体..
比如说人是一个类...人说起人...你想到的是什么???
人是不是包括你我他...
而你就是一个对象....先只要知道这个就行了..
理解了类与对象...学起来会得心应手....看代码也比较轻松...
