Question

所以我需要做的就是能够从文本文件中搜索房间，并显示与我搜索的内容相关的任何匹配项。代码运行良好的问题（房间类型，最低和最高价格，阳台和休息室），但最后，它所做的只是采取文本文件中的第一个房间，并将值更改为我搜索的，（显然我只想找到房间，而不是改变它们的任何内容）。不知道我哪里出错了，为什么它只找到第一个房间并在我不想要的时候改变它。任何帮助将不胜感激，谢谢！

private static void reserveRoom() throws FileNotFoundException {
        Scanner s = new Scanner (System.in);    
        Scanner ROOMS = new Scanner (new FileReader("rooms.txt"));

        int roomnumber = ROOMS.nextInt();
        String roomtype = ROOMS.next();
        double roomprice = ROOMS.nextDouble();
        Boolean hasbalcony = ROOMS.nextBoolean();
        Boolean haslounge = ROOMS.nextBoolean();

        System.out.println(" ");

        System.out.println("--Seach Rooms--" + "\n");

        System.out.println("Room Type (Single/Double/Suite):");
        roomtype = s.nextLine();
        System.out.println(" ");


        System.out.println("Minimum Price: ");
        roomprice = s.nextDouble();
        System.out.println(" ");

        System.out.println("Highest Price: ");
        roomprice = s.nextDouble();
        System.out.println(" ");

        System.out.println("Balcony Preferred?: ");
        hasbalcony = s.nextBoolean();
        System.out.println(" ");

        System.out.println("Has Lounge?: ");
        haslounge = s.nextBoolean();

        System.out.println(" ");

        System.out.println("Searching...");

        System.out.println(" ");

        System.out.printf("Room Number: %s,  Room Type: %s,   Room Price: £%.2f,   Has Balcony: %s, Has Lounge: %s" + "\n", roomnumber, roomtype, roomprice, hasbalcony, haslounge);

        System.out.println("--------------------------------------------------------------------------------------------------- " + "\n");
