Only first requirement are met - but it works in external IDE

Question about the task

Under discussion

Hi Does anyone have an idea why codegym doesn´t match the requirements? I have double-checked my code in eclipse and it process files as requested. Cheers Eike

Read 3 file names from the console: file1, file2, file3.
Split file1 as follows:
Write the first half of its bytes to file2,and write the second half of its bytes to file3.
If the number of bytes in file1 is odd, then file2 should contain the larger half.
Close the streams.

Requirements:

The program should read a file name three times from the console.
Use FileInputStream to read from a file, and use FileOutputStream to write to files.
The first half of the bytes in the first file must be written to the second file.
The second half of the bytes in the first file must be written to the third file.
The FileInputStream and FileOutputStream must be closed.

package com.codegym.task.task18.task1808; import java.io.BufferedReader; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStreamReader; /* Fix the bugs */ public class Solution { public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String file1 = reader.readLine(); String file2 = reader.readLine(); String file3 = reader.readLine(); FileInputStream inputStream1 = new FileInputStream(file1); FileInputStream inputStream2 = new FileInputStream(file1); FileOutputStream outputStream1 = new FileOutputStream(file2); FileOutputStream outputStream2 = new FileOutputStream(file3); int count = 0; int firstBytes = 0; int secondBytes = 0; int sum = 0; int readByte = 0; while (inputStream1.available() > 0) { inputStream1.read(); sum++; } if(sum%2 != 0) { // System.out.println("ODD: " + inputStream2.available() ); while (inputStream2.available() > 0) { readByte = inputStream2.read(); count++; if(count <= (sum / 2 )) { outputStream1.write(readByte); firstBytes++; }else { outputStream2.write(readByte); secondBytes++; } } }else { // System.out.println("EVEN: " + inputStream2.available() ); while (inputStream2.available() > 0) { readByte = inputStream2.read(); count++; if(count <= sum/2) { outputStream1.write(readByte); firstBytes++; }else { outputStream2.write(readByte); secondBytes++; } } } // System.out.println("firstBytes " + firstHalf); // System.out.println("secondBytes " + secondHalf); inputStream1.close(); inputStream2.close(); outputStream1.close(); outputStream2.close(); } }

hi, About the second and last task: You create 2 x FileInputStream on line 19.20, but you only have to create it once;
