Cannot get string

Hi, what is wrong here ? I guess this is not passing because I get int datas ... How can I convert it to String ?

package fr.codegym.task.task13.task1318; import java.io.*; import java.util.Scanner; /* Lecture d'un fichier */ public class Solution { public static void main(String[] args) throws IOException { // écris ton code ici BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String nomFichier = reader.readLine(); InputStream fileInputStream = new FileInputStream(nomFichier); while (fileInputStream.available() > 1) { int data = fileInputStream.read(); System.out.println(data); } reader.close(); fileInputStream.close(); } }

Either 1) you read in everything into a byte[] buffer, then you can convert that to a string. or 2) instead of printing out the int 'data' on line 20, you can convert 'data' to a char and print that instead. It should be print() and not println()

Hm, I tried with the byte[] buffer, but still saying there is not enough lines , however my file is printed entirely ... Thank you for your suggestions , I learn a lot. I will try the character method later. I put the code here, just in case someone is interrested:

public class Solution {
    public static void main(String[] args) throws IOException {

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String nomFichier = reader.readLine();

        InputStream fileInputStream = new FileInputStream(nomFichier);
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

        byte[] byteBuffer = new byte[16];
        int len=fileInputStream.read(byteBuffer);

        while (fileInputStream.available() > 0) {
                byteArrayOutputStream.write(byteBuffer, 0, len);
        }

        System.out.print(new String(byteBuffer));

        fileInputStream.close();
        reader.close();
    }
}

solution

your buffer can only hold 16 bits. What if the file is 17 or more?

Thank you mate ! I just replaced 16 with fileInputStream.available() and it worked

Sorry this is

while (fileInputStream.available() > 0)

But still can't pass and I have the same problem anyway
