哪位学过C++，小弟我来请问个java有关问题！

哪位学过C++，我来请教个java问题！！
我现在水平浅，只接触到一个java文件，这个文件应该是相当于C++中的CPP文件。 java中有没有类似于C++的.H文件的文件？

下面的代码我是放在一个java文件中的，如果要分开存放，应该怎么操作软件，我用的是Eclipse软件。代码是否有需要修改的地方

Java code

import java.io.Console;import java.util.*;import java.lang.System;import java.math.BigInteger;import java.io.*;public class EmployeeTest{    public static void main(String[] args)    {        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("Tone Tester", 40000, 1990, 3, 15);                for(Employee e : staff)            e.raiseSalary(5);                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, 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;}

[解决办法]
在Java中 .Java 就是相当于 C++ 的 .h 和 .cpp
在C++中 类 要用 .h 声明 .cpp定义
而在Java中.java 就可以实现上面的功能。

Java code

//file Employee.javaimport java.io.Console;import java.util.*;import java.lang.System;import java.math.BigInteger;import java.io.*;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;}//file EmployeeTest.javaimport java.io.Console;import java.util.*;import java.lang.System;import java.math.BigInteger;import java.io.*;public class EmployeeTest{    public static void main(String[] args)    {        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("Tone Tester", 40000, 1990, 3, 15);                for(Employee e : staff)            e.raiseSalary(5);                for(Employee e : staff)            System.out.println("name = " + e.getName() + " ,salary=" + e.getSalary() + "hireDay="                    + e.getHireDay() );    }}
[解决办法]
1，随便建个package 例：test
2，新建Employee.java,内容如下：
Java code
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;} 
 
[解决办法]
随便新建个类就可以了，.h文件，就好比是java的interface
[解决办法]
我倒觉得.h文件相当于import.*中的*
[解决办法]
这个与c++不太一样，不如就按照Java的思想来把。

和4楼想法一样
