?Arrays.sort()方法可對任何實現compareble接口的對象數組排序。?

源代碼?

EmployeeSortTest.java

import java.util.*;/*** This program demonstrates the use of the Comparable interface.* @version 1.30 2004-02-27* @author Cay Horstmann*/ public class EmployeeSortTest {public static void main(String[] args){Employee[] staff = new Employee[3];staff[0] = new Employee("Harry Hacker", 35000);staff[1] = new Employee("Carl Cracker", 75000);staff[2] = new Employee("Tony Tester", 38000);Arrays.sort(staff);// print out information about all Employee objectsfor (Employee e : staff)System.out.println("name=" + e.getName() + ",salary=" + e.getSalary());} }

Employee.java
