Question

为什么工资中的值没有从Salary方法解析为Commission方法？

package salesrepresentativeapp;

import java.util.Scanner;

public class SalesRepresentativeAPP {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        String ID;
        String name;
        int yearServiced;
        double salesVolume;

        //System.out.println("Please enter your ID : ");
       // ID = sc.nextLine();
       // System.out.println("Please enter your Name : ");
       // name = sc.nextLine();
        System.out.println("Please enter your Year of Service : ");
        yearServiced = sc.nextInt();
        System.out.println("Please enter your sales volume : ");
        salesVolume = sc.nextDouble();

        SalesRepresentative s1 = new SalesRepresentative("id", "name", yearServiced, salesVolume);

        //System.out.println("ID : " + s1.getID() + "\nName : " + s1.getName());
        System.out.println("Your total salary is : " + s1.Commision() + "\nBasic Salary is : " + s1.Salary());

    }

}

package salesrepresentativeapp;

/**

public class SalesRepresentative {

     private String ID;
     private String name;
     private int yearServiced,salary;
     private double salesVolume,commision;


    public SalesRepresentative(String ID, String name, int yearServiced, double salesVolume){
        this.ID = ID;
        this.name = name;
        this.yearServiced = yearServiced;
        this.salesVolume = salesVolume;
    }

    public int Salary(){
        if (yearServiced >=1 && yearServiced <= 5) {
            salary = 1200;
        }
        else if (yearServiced >=6 && yearServiced <= 10 ) {
            salary = 1800;
        }
        else if (yearServiced > 10) {
            salary = 2300;
        }
        return salary;
    }

    public double Commision(){
         if (salesVolume >= 1 && salesVolume <= 99.99) {
            commision = salary + (salary * 0.05);
        }
        else if (salesVolume >= 100.00 && salesVolume <= 299.99 ) {
            commision = salary + (salary * 0.10);
        }
        else if (salesVolume >= 300.00) {
            commision = salary + (salary * 0.15);
        }
        return commision;
    }

    public String getID(){
        return ID;
    }

    public String getName(){
        return name;
    }
}

当我没有将薪水放在等式中时，该方法运作良好。但是当我把薪水放在等式中时，方法返回值为0.0

Answer 1

首先调用Commision方法，在调用Salaray后编辑该值。改为将System.out改为此。

 System.out.println("Basic Salary is : " + s1.Salary() + "\nYour total salary is : " + s1.Commision());

除了该方法之外，名称应以小写字符开头。

编辑：我希望我能正确理解你的问题。

查看您的代码，您应该进行相当多的更改以改进查看已编辑的副本，我将解释

public class SalesRepresentative {

     private String ID;
     private String name;
     private int yearServiced,salary;
     private double salesVolume,commision;


    public SalesRepresentative(String ID, String name, int yearServiced, double salesVolume){
        this.ID = ID;
        this.name = name;
        this.yearServiced = yearServiced;
        this.salesVolume = salesVolume;

        salary();
        commision();
    }

    private void salary(){
        if (yearServiced >=1 && yearServiced <= 5) {
            salary = 1200;
        }
        else if (yearServiced >=6 && yearServiced <= 10 ) {
            salary = 1800;
        }
        else if (yearServiced > 10) {
            salary = 2300;
        }
    }

    private void commision(){
         if (salesVolume >= 1 && salesVolume <= 99.99) {
            commision = salary + (salary * 0.05);
        }
        else if (salesVolume >= 100.00 && salesVolume <= 299.99 ) {
            commision = salary + (salary * 0.10);
        }
        else if (salesVolume >= 300.00) {
            commision = salary + (salary * 0.15);
        }
    }

    public double getCommision()
    {
        return commision;
    }

    public int getSalary()
    {
        return salary;
    }

    public String getID(){
        return ID;
    }

    public String getName(){
        return name;
    }
}

按照惯例，您的方法名称应该是驼峰式的。我已将其范围从public更改为private（意味着只能在此类中调用）并在构造函数中调用它们。您调用这些方法的顺序非常重要，因为在计算工资之前无法计算佣金。

此外，由于方法正在更新类中的值，我已将其返回类型更改为void。我创建了两个getter方法getSalary()＆amp; getCommission() - 您的应用程序将调用这些值来返回值。请参阅以下实施：

public class SalesRepresentativeAPP {
    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        String ID;
        String name;
        int yearServiced;
        double salesVolume;

        System.out.println("Please enter your Year of Service : ");
        yearServiced = sc.nextInt();
        System.out.println("Please enter your sales volume : ");
        salesVolume = sc.nextDouble();

        SalesRepresentative s1 = new SalesRepresentative("id", "name", yearServiced, salesVolume);

        System.out.println("Your total salary is : " + s1.getCommision() + "\nBasic Salary is : " + s1.getSalary());

    }

}

将值从方法传递到方法
