Java程序怎么写，求指点

各位大神帮帮忙，感谢大家！

public class Employee{
    private String eid;
    private double salary;

    public void setEid(String eid) {
        this.eid = eid;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }

    public static void main(String[] args) {
        Employee emp = new Employee();
        emp.setEid("012");
        emp.setSalary(1122.3);
        System.out.println("员工"+emp.eid+"的工资为"+ emp.salary);
    }
}

测试结果:
员工012的工资为1122.3
