I need help with the code in Java for the following used pattern and matcher from java.util.regex to setup a pattern to find anything that doesn't match the pattern and asks the user to rename the file if it is not within the pattern. For the rule use conservation file naming conventions. Also can you find all the vulnerabilities and mitigation in the given code with test of the mitigations of the new code

 

*/ 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()); } } }
