package com.test;

import java.util.Vector;

import com.domain.Employee;

public class MyVector {
public static void main(String[] args) {
// 创建对象数组，大小为5
Employee[] employee = new Employee[5];
employee[0] = new Employee("NO1", "Tom", 4000);
employee[1] = new Employee("NO2", "Sherry", 4400);
employee[2] = new Employee("NO3", "Rose", 3600);
employee[3] = new Employee("NO4", "Smith", 5600);
employee[4] = new Employee("NO5", "Mary", 4680);
// 创建向量
Vector<Employee> employeeVector = new Vector<Employee>();
// 循环添加员工对象到向量中
for (int i = 0; i < employee.length; i++) {
employeeVector.add(employee[i]);
}
System.out.println("编号\t姓名\t工资");
// 遍历，输出数据
for (Employee emp : employeeVector) {
System.out.print(emp.getsNo() + "\t");
System.out.print(emp.getsName() + "\t");
System.out.println(emp.getSalary());
}
}
