以下是ticket类的定义：package search; import java.util.Date; public class ticket { private int id; private String number; private String wherestart; private String gotowhere; private Date start_time; private Date end_time; private int counts; private double price; private Date order_time; public void setId(int id) { this.id=id; } public int getId() { return id; } public void setNumber(String number) { this.number=number; } public String getNumber() { return number; } public void setWherestart(String wherestart) { this.wherestart=wherestart; } public String getWherestart() { return wherestart; } public void setGotowhere(String gotowhere) { this.gotowhere=gotowhere; } public String getGotowhere() { return gotowhere; } public void setStart_time(Date start_time) { this.start_time=start_time; } public Date getStart_time() { return start_time; } public void setEnd_time(Date end_time) { this.end_time=end_time; } public Date getEnd_time() { return end_time; } public void setAirEnterPrice(double price) { this.price=price; } public double getAirEnterPrice() { return price; } public void setCounts(int counts) { this.counts=counts; } public int getCounts() { return counts; } public void setOrder_time(Date order_time) { this.order_time=order_time; } public Date getOrder_time() { return order_time; } }，如何把上述的string 数组selectedTickets中的数据存入ticket数组tickets

首先，我们需要将`ticket`类的定义放在与`Servlet`同一个包下，然后修改`ticket`类的定义，为`ticket`类添加一个`selected`属性，用于标记该机票是否被用户选择。修改后的`ticket`类定义如下：

package search;

import java.util.Date;

public class ticket {

    private int id;
    private String number;
    private String wherestart;
    private String gotowhere;
    private Date start_time;
    private Date end_time;
    private int counts;
    private double price;
    private Date order_time;
    private boolean selected; // 新增属性

    public void setId(int id) {
        this.id = id;
    }

    public int getId() {
        return id;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getNumber() {
        return number;
    }

    public void setWherestart(String wherestart) {
        this.wherestart = wherestart;
    }

    public String getWherestart() {
        return wherestart;
    }

    public void setGotowhere(String gotowhere) {
        this.gotowhere = gotowhere;
    }

    public String getGotowhere() {
        return gotowhere;
    }

    public void setStart_time(Date start_time) {
        this.start_time = start_time;
    }

    public Date getStart_time() {
        return start_time;
    }

    public void setEnd_time(Date end_time) {
        this.end_time = end_time;
    }

    public Date getEnd_time() {
        return end_time;
    }

    public void setAirEnterPrice(double price) {
        this.price = price;
    }

    public double getAirEnterPrice() {
        return price;
    }

    public void setCounts(int counts) {
        this.counts = counts;
    }

    public int getCounts() {
        return counts;
    }

    public void setOrder_time(Date order_time) {
        this.order_time = order_time;
    }

    public Date getOrder_time() {
        return order_time;
    }

    public void setSelected(boolean selected) {
        this.selected = selected;
    }

    public boolean isSelected() {
        return selected;
    }
}

接下来，在`Servlet`中定义一个`List`类型的变量`tickets`，用于存储用户选择的机票对象。然后通过以下代码来将`selectedTickets`数组中的数据存入`tickets`数组中：

List<ticket> tickets = new ArrayList<>();
if (selectedTickets != null) {
    for (ticket t : ticketList) {
        for (String selectedTicket : selectedTickets) {
            if (String.valueOf(t.getId()).equals(selectedTicket)) {
                t.setSelected(true); // 将用户选择的机票标记为已选择
                tickets.add(t); // 将已选择的机票添加到tickets数组中
            }
        }
    }
}

以上代码首先对`tickets`进行了初始化，然后对`ticketList`（一个包含所有机票对象的列表）进行`for`循环遍历，对于每个机票对象，再对`selectedTickets`数组进行`for`循环遍历，判断该机票对象是否被用户选择，如果是，就将该机票对象的`selected`属性设置为`true`，并将该机票对象添加到`tickets`数组中。这样，`tickets`数组就存储了用户选择的机票对象。
