最大搜索因子和平均搜索因子java

Question

我需要在表格中找到最大搜索因子和平均搜索因子。

我有应该是什么的统计数据，我的统计数据不断超出给定的数据。

public void printStatistics() {
    int numFilledLocations = 0;
    for (Hash hash: hashTable) {
        if (!hash.val.isEmpty()) {
            numFilledLocations++;
        }
    }
    System.out.println("Load Factor: " + ((float) numFilledLocations) / (float) tableSize);
    int maxLength = 0;
    int totalLengths = 0;
    for (Hash hash: hashTable) {
        int length = 1;
        Hash nextHash = hash;
        while (nextHash.next != -1) {
            length++;
            nextHash = hashTable[nextHash.next];
        }
        if (length > maxLength) {
            maxLength = length;
        }
        totalLengths += length;
    }
    System.out.println("Sum of length linked list: " + totalLengths);
    System.out.println("Maximum Search Factor: " + maxLength);
    System.out.println("Average Search Factor: " + ((float) totalLengths / (float) tableSize));
}
