JAVA--第八周实验--接口的练习

题目：

（1）封装一类接口ComputerWeight，该接口中有3个功能：double computrWeight，void printName，double printPrice。

（2）封装一类接口ComputerCompany，该接口有2个功能：String computerName，void printFunction。

（3）封装一类对象FlashMemory实现上述两类接口。

（4）用一个程序执行入口Test测试上述对象。

 

接口ComputerWeight

 

package interface1;

public interface ComputerWeight {
double computerWeight = 6;
void printName();
void printPrice();

}

接口ComputerCompany

package interface1;

public interface ComputerCompany {
String computerName = "lenovel";
void printFunction();
}

 

一类对象FlashMemory

package interface1;

public class FlashMemory implements ComputerWeight,ComputerCompany{

@Override
public void printName() {
// TODO Auto-generated method stub
System.out.println("The computer name is "+computerName);
}

@Override
public void printPrice() {
// TODO Auto-generated method stub
System.out.println("The computer Price is 6000 yuan");
}

@Override
public void printFunction() {
// TODO Auto-generated method stub
System.out.println("Achieve print function");
}

}

程序执行入口Test

package interface1;

public class Test {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
FlashMemory FM = new FlashMemory();
FM.printName();
FM.printPrice();
FM.printFunction();
}

}

 

运行结果：
