在写入文本文件期间，在Java中的Nth Rows之后拆分成新文件？

Question

假设我有 105条记录，我想在文本文件中写下所有记录，其中每个文件中将有 10条记录。

所以总文件将在这里生成11.

Answer 1

Try this

    int count = 0; String filename = "text1";
    for (int i = 0; i <= 105; i++) // loop to 105 times
    {
       count++;
       if(count <= 10) //write 10 records to the file
       {
            if(count == 1)
                filename = "text" + (i/10); 

            try(PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(filename, true)))) {
            out.println("the text");

            }catch (IOException e) {}
            if(count == 10)
                count = 0;
       }
    }

Answer 2

public static void writeToMultipleFiles(int numberOfLines, String prefix, List<String> records){
    lineCounter = 1;
    counter = 1;
    String filename = prefix + counter; 
    for (String line : records){
        if(lineCounter = numberOfLines){
            lineCounter = 1;
            counter++;
            filename = prefix + counter;
        }
        try(PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(filename, true)))) {
            out.println(line);
            lineCounter++;
        }catch (IOException e) {}

    }
}
