Java 编译程序以进行测试时引发异常

通过计算a.txt中的每周总小时数，然后查看他们是否高于该周的平均志愿者小时数，并为这两项评分，从而计算出年度志愿者。我抛出了一个异常，一个数组超出了边界，我不知道为什么

public class volunteerOfTheYear {
//declaring int name for indexing because the name will always be in the first
//postion of the array at nameOfArray[i][0]
final static int NAME = 0;

    Scanner input = getInput(inputText);
    //convert file to 2-d array
    String[][] volunteerChart = getvolunteerChart(input);
    //calculate weekly averages and store in array for comprarison
    double[] weeklyAverages = new double[53];
    int week = 1;
    do{
        weeklyAverages[week] = getAverageWeeklyHours(volunteerChart, week);
        week++;
    }while(week < 52);

}Java和大多数其他语言中的数组从0而不是1索引，因此最高索引比数组大小小一个

因此，当周=52时，getVolunteerPoints中的weeklyAverages[周+1]可以越界。

那么，我是在循环中使用一个单独的计数器，还是从周中减去1？将周限制为51，最大值为周=0；周<52周；或者加入一个if函数，在第52周做一些不同的事情。没有第53周，所以你必须决定你的逻辑是如何处理的。异常被抛出到哪里去了？线程主java.lang.ArrayIndexOutOfBoundsException中的异常：25在jasonsiboleproject4.年度志愿者。GetAverage Weekly在jasonsiboleproject4.年度志愿者.年度主要志愿者。java:39 java结果：1和什么第93行是否？？？weeklyAverages[周]=GetAverageWeeklyHoursvolunterChart，week；不，第93行在方法getAverageWeeklyHours内，异常堆栈可以清楚地看到这一点。
