Read From File

i had wrot this code , and i would like to share it with you :

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;


public class FileRead{

  // condtractore---------------------------------------------------------------
  public FileRead()
  {
    setFileName("");
  }

  // condtractore---------------------------------------------------------------
  public FileRead(String FileName)
  {
    setFileName(FileName);
  }

  //the variable
  private File file;

  // set a file name------------------------------------------------------------
  public void setFileName(String FileName)
  {
    file = new File(FileName);
  }

  public boolean isExsists()
  {
  if (file.exists()){return true;}
  else
    {
      System.out.println("File Does not exsist");
      return false;}
  }

  //read a file-----------------------------------------------------------------
  public String readFile()
  {
    if(!isExsists()){return null;}
     try{
    BufferedReader input = new BufferedReader(new FileReader(this.file));
    String text= new String("");
    StringBuffer buffer = new StringBuffer();
    while((text = input.readLine()) != null)
     {
       text +="\n";
       buffer.append(text);
     }
     return buffer.toString();

                }// end try
                catch(IOException ioException)
                {
                  JOptionPane.showMessageDialog(null,"File Error","File Error",JOptionPane.ERROR_MESSAGE );
                  return "";
                }// end catch
  }//end  read a file method

  // read file directrly--------------------------------------------------------
  public String readFile(String FileName)
      {
      this.setFileName(FileName);
      return (this.readFile());
      }// end read file directrly

  //pritn the content of a file-------------------------------------------------
  public void printFile()
  {
  String OutPut = new String("");
  OutPut = this.readFile();
  System.out.println(OutPut);
  }// end pritn the content of a file

  //pritn the content of a file-------------------------------------------------
  public void printFile(String FileName)
  {
    String OutPut = new String("");
    OutPut = this.readFile(FileName);
    System.out.println(OutPut);

  }// end pritn the content of a file




// the main method
  public static void main(String[] args) {
    System.out.println("\n\n\tStart the main Method:\n");

    // the call for the classes start from hear ---VV--V--Vv ----vV-------------

    FileRead file = new FileRead("MyFile.txt"); //<-- "MyFile.txt" is name of an exsisting file
    file.printFile();

    // the call for the classes end hear ------------^^-^^^---^-^^^^^-----------

  }//end the main method

}// end FileRead class

and if there is any questions about the code , just ask :)
