电影院

一、xml列表

<?xml version="1.0" encoding="UTF-8"?>
<movies>
	<movie>
	    <name>卧虎藏龙</name>
	    <director>李安</director>
		<actor>周润发</actor>	
		<price>120</price>
		<schedule>
		   <item>09:00</item>
		   <item>13:00</item>
		</schedule>
	</movie>
	<movie>
	    <name>盗墓笔记</name>
	    <director>南派三叔</director>
		<actor>鹿晗</actor>	
		<price>80</price>
		<schedule>
		   <item>11:00</item>
		</schedule>
	</movie>
</movies>

二、电影类

package cn.com.cinema;

/*
 * 影片类
 */
public class Movie {

	private String name; // 影片名称
	private String director; // 影片导演
	private String actor; // 影片主演
	private Integer price; // 影片价格
	private String scheduleTime;// 影片放映时间

	public Movie() {
	}

	public Movie(String name, String director, String actor, Integer price,
			String scheduleTime) {
		super();
		this.name = name;
		this.director = director;
		this.actor = actor;
		this.price = price;
		this.scheduleTime = scheduleTime;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getDirector() {
		return director;
	}

	public void setDirector(String director) {
		this.director = director;
	}

	public String getActor() {
		return actor;
	}

	public void setActor(String actor) {
		this.actor = actor;
	}

	public Integer getPrice() {
		return price;
	}

	public void setPrice(Integer price) {
		this.price = price;
	}

	public String getScheduleTime() {
		return scheduleTime;
	}

	public void setScheduleTime(String scheduleTime) {
		this.scheduleTime = scheduleTime;
	}

}

四、测试类

package cn.com.cinema;
public class Test {
	public static void main(String[] args) {
		new CinemaMgr().start();//启动
	}
}
