abstractchinabank.java

有一个接口,用抽象类实现它的部分功能,再用实现类继承抽象类,实现其它没实现的接口方法

package cn.edu.csu.oo.abstractoper.templetePattern;

public abstract class AbstractChinaBank extends Bank{
  public long time;
  public void setTime(long time){
    this.time = time;
  }
  public long getTime(){
    return time;
  }
  public double calculateInterest(){
    interest = getFund()*getInterestRate()* getTime();
    System.out.println(interest);
    return interest;
  }
}
