前面学过接口的基本使用了,本节细化了一下接口的使用方法
package net.edaibu.kotlintest.ClassAndExtends/** * Created by {GEQIPENG} on 2017/5/24 at 15:42 * 接口 */interface TestInterface{ fun getKotlin() fun getJava()}//接口类的实现class MyClass:TestInterface { override fun getKotlin() { println("getKotlin") } override fun getJava() { println("getJava") }}//接口中的属性interface TestInterface2{ var property1:Int fun foo(){ print(property1) }}//继承包含属性的接口,一定要初始化class MyClass2 :TestInterface2{ override var property1: Int=100}//解决重写冲突interface interfaceA{ fun read(){ print("read English") } fun write(){ print(){ print("write word") } }}interface interfaceB{ fun read(){} fun write()}//注意接口中的方法如果有方法体,继承的类不用重写该方法,如果接口中的方法没有方法体,则要重写该方法class MyClass3:interfaceB{ override fun write() { TODO("not implemented") //To change body of created functions use File | Settings | File Templates. }}//如果类同时实现多个接口,则要重写接口中的所有方法,主意:同名方法重写一个即可class MyClass4:interfaceA,interfaceB{ override fun write() { TODO("not implemented") //To change body of created functions use File | Settings | File Templates. } override fun read() { TODO("not implemented") //To change body of created functions use File | Settings | File Templates. }}
