JAVA高手帮忙

老师的作业，帮忙啊

•写以下类： • 飞机：型号，最大座位数，最大航程。 • 航班：航班号，航空公司名称，航空公司代号，航班日期，出发地，目的地， • 起飞时间，到达时间，里程，使用飞机，剩余座位，全价，折扣率。 • 方法：setPlane(Plane p); • 客户：姓名，身份证号，帐户余额。 • 方法：order(Flight f); 要代码啊，谢谢大家了

为了统一，都使用汉语拼音

下面是三个类，类中的两个方法你自己实现。

class plane
{
private String xinghao;
private String zuidazuoweishu;

public plane()
