Question

我似乎在向屏幕显示座位号时遇到问题当我编译它告诉我存储在字符串中的每个数字都是问题

class AirlineSystem{

static int name;

public static void main(String[]args)
            {
String[][] seats = new String[30][6] = {"1a","2a","3a","4a","5a","6a","7a","8a","9a","10a"},
                                        {"11b","12b","13b","14b","15b","16b","17b","18b","19b","20b"},

for(i=0;i=seats.length;i++){
System.out.print("Planes seating arrangements"+[seats]);
}

printarray(seats);
}

Answer 1

我认为您试图以错误的方式访问数组，在java中尝试访问需要执行此操作的数组元素时

array[index]

因此您需要将for循环更改为：

for(i=0;i=seats.length;i++){
    System.out.print("Planes seating arrangements"+seats[i]);
}

但由于它是一个二维数组，你需要有嵌套循环来遍历你的列/行

希望有所帮助，但在发布堆栈溢出之前请先查看这些内容。

Answer 2

不像你正在使用String [] []席位。

所以使用嵌套for循环来进行retreival

示例：

for（）{

for（）{}}

并且座位[i] [j];

Answer 3

您的代码有很多错误。试试这种方式：

public static void main(String[] args) {
    String[][] seats = new String[][] {
            { "1a", "2a", "3a", "4a", "5a", "6a", "7a", "8a", "9a", "10a" },
            { "11b", "12b", "13b", "14b", "15b", "16b", "17b", "18b", "19b", "20b" },
            { "21c", "22c", "23b", "24b", "25b", "26b", "27b", "28b", "29b", "30b" },
            { "31d", "32d", "33d", "34d", "35d", "36d", "37d", "38d", "39d", "40d" },
            { "41e", "42e", "43e", "44e", "45e", "46e", "47e", "48e", "49e", "50e" },
            { "51f", "52f", "53f", "54f", "55f", "56f", "57f", "58f", "59f", "60f" },
            { "61g", "62g", "63g", "64g", "65g", "66g", "67g", "68g", "69g", "70g" },
            { "71h", "72h", "73h", "74h", "75h", "76h", "77h", "78h", "79h", "80h" },
            { "81i", "82i", "83i", "84i", "85i", "86i", "87i", "88i", "89i", "90i" },
            { "91j", "92j", "93j", "94j", "95j", "96j", "97j", "98j", "99j", "100j" },
            { "101k", "102k", "103k", "104k", "105k", "106k", "107k", "108k", "109k", "110k" },
            { "111l", "112l", "113l", "114l", "115l", "116l", "117l", "118l", "119l", "120l" },
            { "120m", "122m", "123m", "124m", "125m", "126m", "127m", "128m", "129m", "130m" },
            { "131n", "132n", "133n", "134n", "135n", "136n", "137n", "138n", "139n", "140n" },
            { "141o", "142o", "143o", "144o", "145o", "146o", "147o", "148o", "149o", "150o" },
            { "151p", "152p", "153p", "154p", "155p", "156p", "157p", "158p", "159p", "160p" },
            { "161q", "162q", "163q", "164q", "165q", "166q", "167q", "168q", "169q", "170q" },
            { "171r", "172r", "173r", "174r", "175r", "176r", "177r", "178r", "179r", "180r" } };

    for (int i = 0; i < seats.length; i++) {
        System.out.println("Planes seating arrangements " + Arrays.toString(seats[i]));
    }
}

Answer 4

试试这个：

String[][] seats = {{"1a","2a","3a","4a","5a","6a","7a","8a","9a","10a"},
                                        {"11b","12b","13b","14b","15b","16b","17b","18b","19b","20b"},

                                        {"71h","72h","73h","74h","75h","76h","77h","78h","79h","80h"},
                                        {"81i","82i","83i","84i","85i","86i","87i","88i","89i","90i"},
                                        {"91j","92j","93j","94j","95j","96j","97j","98j","99j","100j"},
                                        {"101k","102k","103k","104k","105k","106k","107k","108k","109k","110k"},
                                        {"111l","112l","113l","114l","115l","116l","117l","118l","119l","120l"},

                                        {"171r","172r","173r","174r","175r","176r","177r","178r","179r","180r"}
                                };

for(String[] d1: seats) {
    for (String d2 : d1) {
        System.out.printf("%s\t",d2);
    }
    System.out.println();
}

Answer 5

我个人认为以下方法是更好的方法：

public class AirlineSystem
{
  public AirlineSystem()
  {
    final String[][] seats = initializeSeats(18, 10);
    displaySeatingArrangement(seats);
  }

  private String[][] initializeSeats(final int ROWS, final int COLUMNS)
  {
    final String[][] seats = new String[ROWS][COLUMNS];
    int seatIndex = 1;

    for (int i = 0, ch = 'a'; i < ROWS; i++, ch++)
    {
      for (int j = 0; j < COLUMNS; j++)
      {
        seats[i][j] = (seatIndex++) + "" + (char) ch;
      }
    }

    return seats;
  }

  private void displaySeatingArrangement(final String[][] seats)
  {
    System.out.println("Plane Seating Arrangement: ");

    for (String[] row : seats)
    {
      for (String seat : row)
      {
        System.out.printf(" %4s ", seat);
      }

      System.out.println();
    }
  }

  public static void main(String[] args)
  {
    new AirlineSystem();
  }
}

它很好，因为它不需要对座位安排进行硬编码。 for循环以非常紧凑的方式生成排列，并且为了清晰起见，输出也被正确格式化。
