book方法这里总是有问题，不知道是哪里问题，我才学java，以前用C写过类似的，问题怎么解决啊？



import java.util.*;



class Ticket{

	protected String trainNum;

	protected String startCity;

	protected String toCity;

	protected String date;

	protected String startTime;

	protected String toTime;

	protected int seatAccount;

	protected double ticketPrice;

	static int ticketsNum;

	public Ticket(){

		ticketsNum++;	

	}

	public String getTrainNum(){return this.trainNum;}

	public String getStratCity(){return this.startCity;}

	public String getToCity(){return this.toCity;}

	public String getDate(){return this.date;}

	public String getStartTime(){return this.startTime;}

	public String getToTime(){return this.toTime;}

	

	public void setTrainInfo(String tN,String sC, String tC, String d, String sT, String tT, int sA, double tP){

		this.trainNum = tN;

		this.startCity = sC;

		this.toCity = tC;

		this.date = d;

		this.startTime = sT;

		this.toTime = tT;

		this.seatAccount = sA;

		this.ticketPrice = tP;

	}

	public static Ticket[] ticket = new Ticket[2];//current tickets information

	static void currentTrainInfo(){

		for(int i = 0; i < ticket.length; i++){

			ticket[i] = new Ticket();

		}

		ticket[0].setTrainInfo("K000", "Hefei", "Beijing", "12/07", "08:30", "09:30", 50, 34.0);

		ticket[1].setTrainInfo("K111", "Shanghai", "Hefei", "21/07", "09:45", "11:00", 50, 50.5);

	}

	

	static void getTrainsInfo(){

		Ticket.currentTrainInfo();

		System.out.printf("%10s%9s%14s%14s%10s%10s%7s%10s\n", 

							"班   次","日   期","始   发   站","终   点   站","始发时间","到达时间","座位量","票    价");

		for(int i = 0; i < Ticket.ticketsNum; i++){

			System.out.printf("  %-6s%-7s%-10s%-10s%-10s%-9s%-7d%-7.2f\n",ticket[i].trainNum,ticket[i].date,ticket[i].startCity,

					ticket[i].toCity,ticket[i].startTime,ticket[i].toTime,ticket[i].seatAccount,ticket[i].ticketPrice);

		}

	}	

}

class Users extends Ticket{

	protected String userName;

	static int usersNum;

	public Users(){

		super();

		usersNum++;

	}

	public static Users[] users  = new Users[2];

	

	public static void currentUsersInfo(){

		for(int i = 0; i < users.length; i++){

			users[i] = new Users();

		}

	}

	static void book(){

		Users.currentUsersInfo();

		new Users();

		Scanner input = new Scanner(System.in);

		System.out.print("输入姓名：");

		String inputName = input.nextLine();

		users[usersNum].userName = inputName.toString();

		System.out.println("\n可供选择的班次信息入下:");

		Ticket.getTrainsInfo();

		System.out.print("输入班次号: ");

		String inputTrainNum = input.nextLine();

		for(int i = 0; i < Ticket.ticketsNum; i++){

			if(Ticket.ticket[i].getTrainNum() == inputTrainNum){

				;

			}

		}

		

	}



}

class Book extends Ticket{

	

}

public class BookingSystem {

	static void homePage(){

		System.out.println("		***Welcome to Booking System***\n	");

		System.out.println("			1----->	Querying");

		System.out.println("			2----->	Booking");

		System.out.println("			3----->	Returning");

		System.out.print("Please choose: ");	

	}

	public static void main(String[] args){

		Scanner input = new Scanner(System.in);

		BookingSystem.homePage();

		int choice = input.nextInt();

		switch(choice){	

		case 1:

			Ticket.getTrainsInfo();

			break;

		case 2:

			Users.book();

			break;

		}

	}
