条件运算符 ? ： 其他运算符 包括分量运算符 . 、下标运算符[ ]、实例运算符 instanceof、内存分配运算符 new、 强制类型转换运算符(类型)、方法调用运算符()等  课后小作业 请自行总结 Java 运算符的基本用法，包括运算符的优 先级。 大纲 数据类型 常量和变量 关键字与标识符 运算符与表达式 从键盘获得输入 语句 分支结构 循环结构 ���� 数据类型 常量和变量 且与各个case后面的常量表达式值的类型一致 n 每个case一般都有break，若没有则多个case共享一 个分支 n 表达式的值与任何一个case后的常量表达式的值不相 同时执行  课后小作业 自行搜索总结 switch 中的 case 语句如果没有 break 会 出现什么情况，程序逻辑是如何执行的。 2在 Java 1.7 版本之后，switch 里表达式的类型可以为 String。

the HomePage class is the following: package org.wicketTutorial; import org.apache.wicket.request.mapper.parameter.PageParameters; import org.apache.wicket.markup.html.basic.Label; import org.apache.wicket method which returns a score indicating how compatible the request mapper is for the current request. RequestCycle will choose the mapper with the highest score and it will call its mapRequest(Request request) implementations of IRequestMapper and add them to their application via the mount(IRequestMapper mapper) method of the WebApplication class. In paragraph 10.6 we will see how Wicket uses this method to

Hibernate Transactions and Exceptions, along with its IoC approach which allows you to easily swap in mapper/DAO objects implementing data-access functionality, makes it easy to isolate all Hibernate-specific implementations and locations of Hibernate session factories, datasources, transaction managers, and mapper object implementations (if needed). This makes it much easier to isolate and test each piece of persistence-related Service Layer: - application specific 'service' code - works with domain objects, and uses the Mapper API to get those domain objects into and out of some sort of repository (database) - hosted in one
