Java Employee 类实现与基础控制结构解析

Employee 类实现

创建一个名为 Employee 的类，该类包含三个实例变量：名字（字符串类型）、姓氏（字符串类型）和月工资（双精度浮点型）。类中应有一个构造函数来初始化这三个实例变量。为每个实例变量提供设置和获取方法。如果月工资不是正数，则将其设置为 0.0。编写一个名为 EmployeeTest 的测试应用程序，展示 Employee 类的功能。创建两个 Employee 对象并显示每个对象的年薪。然后给每个 Employee 加薪 10%，再次显示每个 Employee 的年薪。

以下是实现上述需求的 Java 代码：

class Employee {
    private String firstName;
    private String lastName;
    private double monthlySalary;

    public Employee(String firstName, String lastName, double monthlySalary) {
        this.firstName = firstName;
        this.lastName = lastName;
        if (monthlySalary > 0) {
            this.monthlySalary = monthlySalary;
        } else {
            this.monthlySalary = 0.0;
        }
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public double getMonthlySalary() {
         monthlySalary;
    }

       {
         (monthlySalary > ) {
            .monthlySalary = monthlySalary;
        }  {
            .monthlySalary = ;
        }
    }
}

   {
        {
            (, , );
            (, , -);

        System.out.println();
        System.out.println(employee1.getFirstName() +  + employee1.getLastName() +  + employee1.getMonthlySalary() * );
        System.out.println(employee2.getFirstName() +  + employee2.getLastName() +  + employee2.getMonthlySalary() * );

        employee1.setMonthlySalary(employee1.getMonthlySalary() * );
        employee2.setMonthlySalary(employee2.getMonthlySalary() * );

        System.out.println();
        System.out.println(employee1.getFirstName() +  + employee1.getLastName() +  + employee1.getMonthlySalary() * );
        System.out.println(employee2.getFirstName() +  + employee2.getLastName() +  + employee2.getMonthlySalary() * );
    }
}
