InputStreamReader Example

import java.io.InputStreamReader;
import java.io.FileInputStream;

class Main {
  public static void main(String[] args) {

    // Creates an array of character
    char[] array = new char[100];

    try {
      // Creates a FileInputStream
      FileInputStream file = new FileInputStream("input.txt");

      // Creates an InputStreamReader
      InputStreamReader input = new InputStreamReader(file);

      // Reads characters from the file
      input.read(array);
      System.out.println("Data in the stream:");
      System.out.println(array);

      // Closes the reader
      input.close();
    }

    catch(Exception e) {
      e.getStackTrace();
