Part II: Fix security issues in a simple Java application that uses command line arguments. 1. Download the source file from this week. Found as an attachment in the homework folder.

2. Create a new Java application in Netbeans and either copy and paste the code or import the existing source file. Note you may need to make package adjustments if you created a different package

Here are text versions of the code and emailaddresses for your reference:

package sdev425;

import java.io.BufferedReader;

import java.io.FileReader;

import java.io.IOException;

/** * * @author jim */ public class SDEV425_1 {

/** * @param args the command line arguments */

public static void main(String[] args) {

// Read the filename from the command line argument String filename = args[0];

BufferedReader inputStream = null;

String fileLine;

try {

inputStream = new BufferedReader(new FileReader(filename));

System.out.println("Email Addresses:");

// Read one Line using BufferedReader

while ((fileLine = inputStream.readLine()) != null) { System.out.println(fileLine); } }

catch (IOException io) { System.out.println("File IO exception" + io.getMessage()); }

finally { // Need another catch for closing // the streams try { if (inputStream != null) { inputStream.close(); } }

catch (IOException io) { System.out.println("Issue closing the Files" + io.getMessage()); }

}

}

}
