如何在java中计算销售佣金

Question

public class Salesman {
    //defining attributes
    private String name;
    private double salesGoal;
    private double totalSold;

    public double calculateCommission() {
        double soldValue;
        if (totalSold <  ) {
            soldValue =(totalSold * 1.01);
        }else if(totalSold >= ){
            soldValue =(totalSold * 1.025);
        }else if(totalSold >= ){
            soldValue =(totalSold * 1.035);
        }else{
            soldValue = 0;
        }

        return soldValue;
    }

}

Answer 1

什么进入，什么退出决定了你的方法签名。

public double calculateCommission(double soldValue, double goal) { 
  return 0d;
}

然后创建某种流程图

public double calculateCommissionRate(double soldValue, double goal) { 
  double ratio = soldValue / goal;

  if (ratio < 0.5) return 0.01;
  if (ratio < 0.7) return 0.025;
  return 0.035;
}

试着把你的目标或销售目标想象成一块蛋糕。您需要知道的是，蛋糕已经售出了多少(ratio=已售出/蛋糕)。这是首先要计算的。

public double calculateCommission(double soldValue, double goal) { 
  double commissionRate = calculateCommissionRate(soldValue, goal);
  return soldValue * commissionRate;
}
