将子类对象赋给父类对象的引用，可以使用在父类对象中定义了的方法和成员。
程序运行时，会根据该对象的实际类型决定调用父类还是子类的方法（动态绑定）。
 
对象的转型（cast） 只能发生在父类与子类之间。
将父类转为子类前最好使用instanceof判断类型是否正确，使用cast的唯一目的应该是在使用父类指代通用子类时，为了使用]]>https://blog.youkuaiyun.com/vicky_fish/article/details/6105503https://blog.youkuaiyun.com/vicky_fish/article/details/6105503vicky_fishWed, 29 Dec 2010 17:27:00 +08001.javac
 
javac 编译一个.java文件，可以在命令行指定文件的路径位置，如：
 
javac d:/java/test.java
 
可用-d 参数指定编译生成的.class文件存放位置
 
当需要编译的.java文件含有package声明，javac并不检查其对应的目录结构是否正确
 
当需要编译的.java(test.java)文件有import 其他包中的类（如vivi.u]]>
