[til 011_001] 객체배열

지금은 잘 쓰이지 않는다고 하는 객체배열.

어제 만들던 회원정보 입력 예제에서 궁금했었던

여러가지 객체들을 입력하고 기억했다가 원하는 데이터를 출력하려면 어떻게 해야할지에대해 답을 알 수 있었던 기능이다.

연습해보기.

employee class

package com.hw1.model.vo;

private int empNo; 
private String empName;

private int salary;
private double bonusPoint;
private String phone;
private String address;
