读取dat文件的最后一行，然后提取出第4列和第14列的内容

Question

问题遇到的现象和发生背景

import java.io.*;
import java.util.Arrays;

public class Read {
    public static void main(String[] args){
        try{
            readFile("D:\\3.dat");
        } catch (IOException e){
            e.printStackTrace();
        }
    }

    private static void readFile(String sourceFilePath ) throws IOException{
        File file = new File(sourceFilePath);
        FileReader fileReader = new FileReader(file);
        BufferedReader bf = new BufferedReader(fileReader);
        String str;
        while ((str = bf.readLine())!=null){
            System.out.println(Arrays.toString(str.split("\\|")));
        }
    }
    


}

下方是dat文件

希望在上面代码基础上修改

出来的结果只有一行的数据为0900038337298和5

Answer 1

System.out.println(Arrays.toString(str.split("\|")));
输出的结果是什么
