文本文件中的字符串读取行不一致

Question

Hi StackOverFlow People,

I have this issue in my development of System, where I have 4451 lines of record in a text file , and I am retrieving it using BufferedReader and split every line by pipe ( | ). I'm using Quartz also to run this reading of file every day. when I test it, I set the quartz job every minute so I can test It if it actually reading the file in every minute. It reads all of the line in the text file by checking it using this.

BufferedReader reader = new BufferedReader((newInputStreamReader(inputStream));
String line = null;
int counter = 0;
while((line = reader.readLine()) != null){
    counter++;
}
System.out.println(counter);

But when I split the String , The result of retrieving 4451 records is inconsistent. Sometimes, It only retrieves 1000+ to 2000+ records, and Sometime it retrieves 4451, but not consistently. This is my code.

try {
BufferedReader reader = new BufferedReader((newInputStreamReader(inputStream));
String line = null;
int counter = 0;
String[] splitLine = null;
while((line = reader.readLine()) != null){
    splitLine = line.split("\\|"); // Splitting the line using '|' Delimiter
    for(String temp : splitLine) {
       System.out.println(temp);
    }
    counter++;
}
System.out.println(counter);
} catch (IOException e) {
   e.printStackTrace();
}

Is the splitting of String and Iterating of the readfile at the same time could be the cause?

EDIT: There's no Exception Occured in the Situation. It Only print the length of by using the counter variable.

My Expected Output is I want to Retrieve all the records per line in the text file and split the string per line by pipe . counter is the count of lines retrieved.

I didn't find any error in your code but the code that I have written is working perfectly fine. Here is the code

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

class Test {
    public static void main(String[] args) {
        FileReader inputStream = null;
        BufferedReader reader = null;
        try {
            inputStream = new FileReader("Input.txt");
            reader = new BufferedReader(inputStream);
            String line = null;
            int counter = 0;
            String[] splitLine = null;
            while ((line = reader.readLine()) != null) {
                splitLine = line.split("\\|"); 
                for (String temp : splitLine) {
                    System.out.println(temp);
                }
                counter++;
            }
            System.out.println(counter);
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

Shouldn't pipe delimiter be just "|" instead of "\\\\|" ?

Try Changing your code to:

splitLine = line.split("|"); // Splitting the line using '|' Delimiter
