Java第四周常用类与集合框架上机实验一接口+抽象类

(http://img.blog.csdn.net/20150907112946909)

第一题：
1、package test9_7;

public abstract class InterfaceTest_phone implements  InterfaceTest {

//  String phoneaction="手机";
String phoneaction ;
public void takepicture() {
System.out.println("*********");
System.out.println("抽象类的InterfaceTest_phone的takepicture()方法中");
System.out.println("￥￥￥￥￥￥￥￥￥￥￥￥");
}
public void picture(String stype) {
this.phoneaction=stype;
System.out.println("这款手机的照相作业是："+this.phoneaction);

}
public abstract void photo();
}
2、package test9_7;

public interface InterfaceTest {

String action="照相";
public void takepicture();
public void picture(String stype);
}

3、package test9_7;

public   class InterfaceTest_picturephone extends InterfaceTest_phone implements  InterfaceTest   {
public static String picture="高像素小清新拍照手机";
public static void main(String[] args){
InterfaceTest_picturephone picturephone=new InterfaceTest_picturephone();

picturephone.takepicturetest();
picturephone.picture(picture);
System.out.println("这时候的功能主要是："+action);
System.out.println("");
picturephone.takepicture();
picturephone.picture("手机");

}

public void takepicturetest() {
System.out.println("%%%%%%%%%%%%%%%%%");
System.out.println(" 类的InterfaceTest_picturephone的takepicture()方法中");
System.out.println("&&&&&&&&&&……………………&&&&&&&");
}

public  void photo(){

}

}
