您当前的位置: 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;
}
------解决方案--------------------
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.java
import 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.java
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() );
}
}

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;
}
