所以我正在阅读一个包含我之前在代码中写入的约会的文件。我想筛选文本文件并找到某个日期的约会并将它们添加到 ArrayList 但是当 BufferedReader 通过它时，它会跳过其他行...这是我的代码

public ArrayList<String> read(int checkDay, int checkMonth, int checkYear) {
    ArrayList<String> events = new ArrayList<String>();
    BufferedReader in = null;
    String read;
    try {
        in = new BufferedReader(new FileReader("calendar.txt"));
        while ((read = in.readLine()) != null) {
            read = in.readLine();

            String[] split = read.split(",");
            System.out.println(read);

            if (split[1].equals(Integer.toString(checkDay)) && split[2].equals(Integer.toString(checkMonth)) && split[3].equals(Integer.toString(checkYear))) {
                events.add(split[0] + " : " + split[1] + "/" + split[2] + "/" + split[3]);
            }

        }
    } catch (IOException e) {
        System.out.println("There was a problem: " + e);
        e.printStackTrace();

    } finally {
        try {
            in.close();
        } catch (Exception e) {
        }

    }
    return events;
}

【解决方案1】：

您正在阅读该行两次..

while ((read = in.readLine()) != null) { // here
            read = in.readLine();      // and here

【解决方案2】：

这里有错误：

while ((read = in.readLine()) != null) 
 read = in.readLine();

您应该暂时保留 read = in.readLine() 。并删除另一行。

请试试这个

你在 while 循环中使用了两次“read = in.readLine())”，这就是为什么它跳过了 lomes

public ArrayList<String> read(int checkDay, int checkMonth, int checkYear) {
        ArrayList<String> events = new ArrayList<String>();
        BufferedReader in = null;
        String read;
        try {
            in = new BufferedReader(new FileReader("calendar.txt"));
            while ((read = in.readLine()) != null) {

                String[] split = read.split(",");
                System.out.println(read);

                if (split[0].equals(Integer.toString(checkDay)) && split[1].equals(Integer.toString(checkMonth)) && split[2].equals(Integer.toString(checkYear))) {
                    events.add(split[0] + " : " + split[1] + "/" + split[2] + "/" + split[3]);
                }

            }
        } catch (IOException e) {
            System.out.println("There was a problem: " + e);
            e.printStackTrace();

        } finally {
            try {
                in.close();
            } catch (Exception e) {
            }

        }
        return events;
