tempinterestrate.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 class TempInterestRate {
  private long time;
  private ChinaBank cb;
  public void setTime(long time){
    this.time = time;
  }
  public TempInterestRate(ChinaBank cb, long time){
    this.time = time;
    this.cb = cb;
  }
  public double calculateInterest(){
    return time*cb.calculateInterest();
  }
  
}
