一个关于静态函数的简单例子

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


staff[0] = new Employee("Tom", 40000);
staff[1] = new Employee("Dick", 60000);
staff[2] = new Employee("Harry", 65000);


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


 int n = Employee.getNextId(); // calls static method
 System.out.println("Next availableHarry", 50000);
 System.out.println(e.getName() + " " + e.getSalary());
 }


 private String name;
 private double salary;
 private int id;
 private static int nextId = 1;
 }
