Simple Java application with Audit file.

Hi all, today I have come up with new simple application based on one of my blog referee’s request.

He asked me to code a simple application that will handle audit file. Normally I do not do anyone’s assignments but this done because I didn’t know how to do it in java. So finally I did it. See the code and explanation on the source code for more details.

This is very simple application that will record the every process of the application (login, button click, etc…) to .dat file. In a big project this will very helpful. I did not use any data encryption method  here.

This is the audit file handling class

package simpleaudit;

public class Audit{  // this is the start audit class

    public void auditIt(String message) throws ClassNotFoundException // method declaration

    {

      BufferedWriter bw = null;

      try {

	  //this pease of code i got from
         //http://www.devdaily.com/java/edu/qanda/pjqa00009.shtml

         bw = new BufferedWriter(new FileWriter("checkbook.dat", true)); // create a new object
	 bw.write(message); // passed the audit message
	 bw.newLine(); //print new line after each statement
	 bw.flush(); // flush the buffer after enter audit details.

      }

      catch (IOException ioe)
      {

      }

      finally
      {
	 if (bw != null) try
         {
	    bw.close();
	 }

         catch (IOException ioe2)

         {

	 }
      }

    }

}
