java - 初始化2d char数组以测试打印时出错

我的飞机座位表无法正确打印。仅当输入预初始化的数组时，我才会收到一长串错误。我不确定我目前在做什么错，但是它不起作用。

import java.util.*;
public class AirplaneSeating
{
    public static void main(String[] args) throws IOException
    {
        Scanner console = new Scanner(System.in);
        int rows = 2;
        int c, c2;
        char[][] seatsLeft = new char[rows][3];
        char[][] seatsRight = new char[rows][3];
        seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
        seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
        System.out.println("        A B C  D E F");
        for (c = 0; c < 6; c++)
        {
            System.out.print("Row  " + (c + 1) + " ");
            for (c2 = 0; c2 < 3; c2++)
            {
                System.out.print(seatsLeft[c2] + " ");
            }
            System.out.print("  ");
            for (c2 = 0; c2 < 3; c2++)
            {
                System.out.print(seatsRight[c2] + " ");
            }
            System.out.println();
        }
    }
}

这是我遇到的错误：

AirplaneSeating.java:11: error: illegal start of expression
    seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
                ^
                                   ^
AirplaneSeating.java:12: error: <identifier> expected
    seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
              ^

编辑：这是到目前为止我已修复的代码，并且我没有更多错误。

import java.util.*;
public class AirplaneSeating
{
    public static void main(String[] args)
    {
        Scanner console = new Scanner(System.in);
        int rows = 3;
        int c, c2;
        char[][] seatsLeft = {{ '-', '-', '-' },{ '-', '-', '-' },
        { '-', '-', '-' }};
        char[][] seatsRight = {{ '-', '-', '-' },{ '-', '-', '-' },
        { '-', '-', '-' }};
        System.out.println("        A B C  D E F");
        for (c = 0; c < rows; c++)
        {
            System.out.print("Row  " + (c + 1) + " ");
            for (c2 = 0; c2 < 3; c2++)
            {
                System.out.print(seatsLeft[c2] + " ");
            }
            System.out.print("  ");
            for (c2 = 0; c2 < 3; c2++)
            {
                System.out.print(seatsRight[c2] + " ");
            }
            System.out.println();
        }
    }
}

但它的输出如下：
       A B C D E F
第1行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69
第2行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69
第3列[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69

最佳答案

你需要这样做

char[][] seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
char[][] seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};

或者像这样循环执行

char[][] seatsLeft = new char[rows][3];
char[][] seatsRight = new char[rows][3];
for(int i=0i<rows;i++){
    for(int j=0;j<3;j++){
        seatsLeft[i][j]='-';
        seatsRight[i][j]='-';
    }
}

你不能这样做

char[][] seatsLeft = new char[rows][3];
char[][] seatsRight = new char[rows][3];
seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};

因为执行char[][] seatsLeft = new char[rows][3];时已经初始化了数组！

如您所见，我们如何使用2个循环进行初始化，您也必须使用2个循环进行打印。

for(int i=0;i<rows;i++){
    System.out.println("Row " + (i + 1));
    for(int j=0;j<3;j++){
        System.out.print(" "+seatsLeft[i][j]);
    }
    System.out.print(" ");
    for(int j=0;j<3;j++){
        System.out.print(" "+seatsRight[i][j]);
    }
    System.out.println("");
}

它会像这样打印出来：ABCDEF第1行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69第2行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69第3行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69

为您服务，因为您必须了解自己在做什么

 System.out.print(seatsLeft[c2] + " ");
 System.out.print(seatsRight[c2] + " ");

您需要了解您正在做的事情是在二维数组上。 seatLeft [c2]＆seatRight [c2]返回您所看到的那一行的地址。
