How to convert character code to character in java?

Question

Java

There is the following code

package test;

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class Main {

  static FileInputStream in = null;
  static BufferedInputStream bin = null;
  
  public static void main(String[] args) throws IOException {
    try {
      in = new FileInputStream(new File("res/text.txt"));
      bin = new BufferedInputStream(in);
      boolean eof = false;
      
      while (!eof) {
        int byteValue =  bin.read();
        System.out.println((char) byteValue +"");
        if (byteValue == -1) {
          eof = true;
        }
      }
      
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } finally {
      in.close();
      bin.close();
    }
  }
}

It reads the file and outputs the character codes from the file. Do you get question marks when you try to cast byteValue to char?
