将输出数据写入文本文件在文本文件中给出不完整的结果

我有 14 个列表，每个列表都有数字或字符串数​​据。每个列表的大小为 32561。我必须输出格式如下的文件：

list1_element1   list2_element1.......................list14_element1
list1_element2   list2_element2.......................list14_element2
.
.
.
.
.
list1_element32561   list2_element32561.......................list14_element32561

输出文件中的每个元素均由制表符空格分隔。我在Java中是这样做的。

        out = new BufferedWriter(new FileWriter(fileName));
        for(int i=0; i<32561; i++) {
        out.write(firstList.get(i));
        out.write("\t");
        out.write(secondList.get(i));
        out.write("\t");
        out.write(thirdList.get(i));
        out.write("\t");
        out.write(fourthList.get(i));
        out.write("\t");
        out.write(fifthList.get(i));
        out.write("\t");
        out.write(sixthList.get(i));
        out.write("\t");
        out.write(seventhList.get(i));
        out.write("\t");
        out.write(eighthList.get(i));
        out.write("\t");
        out.write(ninthList.get(i));
        out.write("\t");
        out.write(tenthList.get(i));
        out.write("\t");
        out.write(eleventhList.get(i));
        out.write("\t");
        out.write(twelvethList.get(i));
        out.write("\t");
        out.write(thirteenthList.get(i));
        out.write("\t");
        out.write(fourteenthList.get(i));
            out.write("\t");
        out.write(fifteenthList.get(i));

        out.newLine();
    }
}

我的程序仅打印 32441 行，最后一行仅包含 6 列。我不明白为什么。有人可以帮忙吗？

你没有关闭Writer，所以你会丢失缓冲区中的所有内容。
