在java中同时编译几个类

来源：百度知道 编辑：UC知道 时间：2024/06/28 07:12:20
我有这样个程序,有两个类:
public class EmployeeTest
{
public static void main(String[] args)
{
// fill the staff array with three Employee objects
Employee[] staff = new Employee[3];

staff[0] = new Employee("Carl Cracker", 75000, 1987, 12, 15);
staff[1] = new Employee("Harry Hacker", 50000, 1989, 10, 1);
staff[2] = new Employee("Tony Tester", 40000, 1990, 3, 15);

// raise everyone's salary by 5%
for (Employee e : staff)
e.raiseSalary(5);

// print out information about all Employee objects
for (Employee e : staff)
System.out.println("name=" + e.getName()
+ ",salary=" + e.getSalary()
+ ",hireDay=" + e.getHireDay());
}
}

class Employee
{
public Employee(String n, double s, int year, int month,

原因是没有import进java.util.Date和java.util.GregorianCalendar两个类

import java.util.Date;
import java.util.GregorianCalendar;

public class EmployeeTest {
public static void main(String[] args) {
// fill the staff array with three Employee objects
Employee[] staff = new Employee[3];

staff[0] = new Employee("Carl Cracker", 75000, 1987, 12, 15);
staff[1] = new Employee("Harry Hacker", 50000, 1989, 10, 1);
staff[2] = new Employee("Tony Tester", 40000, 1990, 3, 15);

// raise everyone's salary by 5%
for (Employee e : staff)
e.raiseSalary(5);

// print out information about all Employee objects
for (Employee e : staff)
System.out.println("name=" + e.getName() + ",salary=" + e.getSalary() + ",hireDay=" + e.getHireDay());
}
}

class Employee {
public Employee(String n, double s, int y
