Reading files in Java

I am going to show example which shows how to read a file in Java.
If you want to read some file you should start with FileInputStream. This class is a concrete subclass of InputStream. It provides an input stream connected to a particular file.
Example:

package tutorial;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.PrintStream;public class Main{ public static void main(String[] args){ FileInputStream fileInputStream = null; try{ String workingDirectory = System.getProperty("user.dir"); File fileDir = new File(workingDirectory,"src/tutorial"); File file = new File(fileDir,"Main.java"); fileInputStream = new FileInputStream(file); show(fileInputStream,System.out); } catch (IOException ex){ } finally{ try{if (fileInputStream != null){fileInputStream.close();}  } catch (IOException ex){}  }  System.out.println(); }  private static void show(FileInputStream fin,PrintStream out) throws IOException{ byte[] buffer = new byte[1024]; while (true){ int bytesRead = fin.read(buffer); if (bytesRead == -1){break; }  out.write(buffer,0,bytesRead); }  }}

Main method here is show(). It is very simple method. In general Java allows to work with all things very easy.
