Java索引越界错误

我的程序中存在索引超出范围的问题。底部方法中的for循环的运行次数应与flightSeatingAmount（）方法中指定的次数相同。但是在运行程序进行测试时，我总是遇到一个错误。有时在出错之前我会得到一到两个输出，而其他时候我没有得到任何输出，只有错误。这是我的密码：

843是指循环应该执行多少次。

您的airportSelectionOne返回45。您的机场阵列中没有46个机场。这意味着您已经远远超过了数组的末尾，这是非法的。更改函数，使其不会返回大于数组大小的数字。提示：您可以通过机场来判断阵列的大小。长度此循环有问题：

for (int i = 0; i <= flightSeatingAmount(); i++) {
        System.out.println(nameGenerator() + "," + "0" + "," + airports[airportSelectionOne()]);
    }

for（int i=0；i更改以下代码以获得正确的数组大小

int airportOne = (int)(Math.random() * [size of airport array - 1]);

public static void flightManifest（）引发FileNotFoundException{
System.out.println（flightSeatingAmount（））；
对于（int i=0；我完全忘记了那个错误。我甚至懒得去看那里。谢谢你的帮助！
int airportOne = (int)(Math.random() * [size of airport array - 1]);

public static void flightManifest() throws FileNotFoundException {

    System.out.println(flightSeatingAmount());
    for (int i = 0; i <= flightSeatingAmount(); i++) {

//GOOD INFORMATION!!!
System.out.println("airportSelectionOne()=" + airportSelectionOne() + ", airports.length=" + airports.length + "");

        System.out.println(nameGenerator() + "," + "0" + "," + airports[airportSelectionOne()]);
    }    
}
