我的飞机座位表打印不正确。只有在输入预先初始化的数组时，我才会得到一长串错误。我不确定我目前做错了什么，但它不起作用。
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();
}
}
}
以下是我遇到的错误：
AirplaneSeating.java:11: error: illegal start of expression
seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
^
^
AirplaneSeating.java:12: error: <identifier> expected
seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
^
编辑：这是我到目前为止修复的代码，我没有更多的错误。
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();
}
}
}
但它打印出来像这样： 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行[C @ 55f96302 [C @ 55f96302 [C @ 55f96302 [C @ 3d4eac69 [C @ 3d4eac69 [C @ 3d4eac69
答案 0 :(得分：1)
你需要这样做
char[][] seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
char[][] seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
或者像
一样循环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 = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
因为您在执行char[][] seatsLeft = new char[rows][3];时已经初始化了数组！
当您看到我们如何使用2循环初始化时，您还必须使用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("");
}
它打印出来像这样：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
对你而言，因为你必须明白你在做什么
System.out.print(seatsLeft[c2] + " ");
System.out.print(seatsRight[c2] + " ");
您需要了解您所做的是在二维阵列上。 seatLeft [c2]＆amp; seatsRight [c2]返回您所看到的那一行的地址。
答案 1 :(得分：1)
此计划中有两个主要问题 - 1.您不需要抛出IOException，或者为了进一步的目的而不需要导入java.io.IOException;
char[][] seatsLeft = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
char[][] seatsRight = {{'-','-','-'},{'-','-','-'},{'-','-','-'}};
如果你想稍后再做，请逐个元素，即char [0] [0] =＆＃39; - ＆＃39;;
如果您进行此修改，您的程序将会运行。
答案 2 :(得分：0)
我在你的代码中看到了一些错误，首先你的数组赋值（使用括号）只允许在数组的初始声明中。使用数组.length属性而不是硬编码长度。然后，要访问和打印二维数组中的字符，请使用两个数组索引。像，
char[][] seatsLeft = { { '-', '-', '-' }, { '-', '-', '-' },
{ '-', '-', '-' } };
char[][] seatsRight = { { '-', '-', '-' }, { '-', '-', '-' },
{ '-', '-', '-' } };
System.out.println(" A B C D E F");
for (c = 0; c < seatsLeft.length; c++) {
System.out.print("Row " + (c + 1) + " ");
for (c2 = 0; c2 < seatsLeft[c].length; c2++) {
System.out.print(seatsLeft[c][c2] + " "); // <-- [c][c2]
}
System.out.print(" ");
for (c2 = 0; c2 < seatsRight.length; c2++) {
System.out.print(seatsRight[c][c2] + " "); // <-- [c][c2]
}
System.out.println();
}
或者，使用for-each和格式化输出
for (c = 0; c < seatsLeft.length; c++) {
System.out.printf("Row %d ", c + 1);
for (char ch : seatsLeft[c]) {
System.out.printf("%c ", ch);
}
System.out.print(" ");
for (char ch : seatsRight[c]) {
System.out.printf("%c ", ch);
}
System.out.println();
}
