+单继承父类并实现多个接口

+2.如果有抽象方法没有实现，那么子类实现类必须是抽象类
+3.如果多个接口中有相同的抽象方法，那么子类实现类只要实现一次即可。
+4.如果多个接口和抽象父类中有相同的抽象方法，那么子类实现类也只要实现一次即可。
+5.如果多个接口有相同的抽象方法，并且在父类中有一个同名的普通方法，
+        那么子类实现类可以不重写接口中的抽象方法，也可以根据需求来重写，类的方法优先于接口

+接口中的内容特点：
+1.抽象方法（jdk7之前）：制定规则，规范
+2.默认方法（jdk8）：优化解决接口升级的问题
+3.静态方法（jdk8）:定义一些可以直接通过接口名调用的方法
+4.私有方法（jdk9）：对默认方法和静态方法共有的代码进行抽取复用，并不让外界调用
+5.常量（jdk7之前）：定义一些可以通过接口名直接访问的值
 
+抽象方法：定义实现类必须遵守的规范；
+默认方法：为实现类提供可选的默认实现；
+静态方法：为接口本身提供辅助工具功能
+私有方法（jdk9）：对默认方法和静态方法共有的代码进行抽取复用，并不让外界调用
+接口常量的作用域是全局可见（public），且不可修改（final）适合定义"公共标准值"。为接口的行为规范提供配套的固定值
