我有一个数据集，它在字符串数组中列出每天完成的不同活动，类似的概念在这里问。每个活动都是分隔的，可以很容易地分成列，因为我在 Excel 中没有问题。

activites
Work | family | date | gaming | relax | good sleep | shopping   
Work | family | date | Nature | Crusin | reading | gaming | relax | good sleep | cooking | laundry  
family | date | movies & tv | gaming | sport | relax | medium sleep | cooking   
Work | family | date | Photography | gaming | relax | good sleep | medium sleep | cooking   
Work | family | date | Nature | reading | gaming | relax | good sleep | cleaning

我想要做的是将每个活动变成一个布尔变量，它有自己的列，因此它表示0当天没有完成活动并且1已经完成了活动。它看起来像这样：

Work   Family   Date   Gaming   Relax
1      1        0      1        0
1      1        1      0        0
0      0        1      0        1

所以，我最终做的是利用我对 Java 的了解来重新格式化数据。我首先将活动分成各自的变量，每个变量都包含一个数字（二进制​​）值，以指示该活动当天是否完成。我不得不单独对待睡眠质量，所以这部分看起来有点不稳定。这是产生正确输出的代码：

    public static void main(String[] args) throws FileNotFoundException {
        Scanner scan = new Scanner(new FileReader("activities.txt"));
        String[] actList = { "Work", "school", "family", "friends", "date", "nature", "crusin", "photography",
                "making music/piano", "movies & tv", "reading", "gaming", "sport", "relax", "sleep", "shopping", "cleaning",
                "cooking", "laundry" };
        int row = 0;
        while (scan.hasNextLine()) {
            row++;
            int col = 0;
            int activityNo = 0;
            int[] actValue = new int[actList.length];
            String pipeDelim = scan.nextLine();
            String[] actName = pipeDelim.split(" \\| ");
            int sleepTagsUsed = 0;
            while (activityNo < actName.length) {
                col = 0;
                for (String a : actName) {
                    if (a.contains("sleep")) {
                        col = 14;
                        if (a.equalsIgnoreCase("bad sleep") || a.equalsIgnoreCase("bad sleep\t")) {
                            if (col < actList.length) {
                                actValue[col] = 0;
                                if (sleepTagsUsed == 0) {

                            }
                            if (!(activityNo > actName.length)) {
                                activityNo++;
                            }
