Java learning
1、利用面向对象的**实现丢手绢游戏。 2、演示多态--一个引用(类型)在不同情况下的多种状态。 3、抽象类存在的必要性--解决父类方法的不确定性。 4、接口--体现程序设计的多态和高内聚低耦合的设计**。 5、实现接口 VS 继承类:继承是先天的能力,实现接口是后天努力获得的 6、对象数组的使用 7、排序算法--冒泡排序法、选择排序法、插入排序法、快速排序法 8、查找算法--二分查找法 9、集合--使用ArrayList实现员工管理系统 10、集合--使用HashMap实现学生管理系统 11、线程使用的两种方式:1、继承Thread类,重写run方法;2、实现Runnable接口,重写run方法 12、多线程编程--线程同步机制(解决线程并发引发的安全问题) 13、文件编程--文件的创建(文件夹是一种特殊的文件) 14、文件编程--字节流实现文件读写操作(可以操作任何文件:二进制文件、文本文件) 15、文件编程--字符流实现文件读写操作(只能操作文本文件) 16、文件编程--缓冲字符流(操作对象为String,效率较字符流更高) 17、Socket网络编程--半双工(服务端) 18、Socket网络编程--半双工(客户端) 19、sql server数据库操作:EmpManage.sql 待续。。。
