------解决方案--------------------
1,随便建个package 例:test
2,新建Employee.java,内容如下:
package test; import java.util.Date; import java.util.GregorianCalendar; public class Employee { public Employee(String n, double s, int year, int month, int day) { name = n; salary = s; GregorianCalendar calendar = new GregorianCalendar(year, month - 1, day); hireDay = calendar.getTime(); } public String getName() { return name; } public double getSalary() { return salary; } public Date getHireDay() { return hireDay; } public void raiseSalary(double byPercent) { double raise = salary * byPercent / 100; salary += raise; } private String name; private double salary; private Date hireDay; }
