Here what you want, do it with busy works. Test and let me know.

Code:

	public static void main(String args[]) throws Exception{
		// TODO Auto-generated method stub		
		String inputFile = null;
		String searchString = null;
		String outputFile = null;

                    System.out.print("Enter Input File: ");
                    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
                    inputFile = br.readLine();		

                    System.out.print("Enter Search String: ");
                    BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));
                    searchString = br1.readLine();		
                    
                    System.out.print("Enter Output File: ");
                    BufferedReader br2 = new BufferedReader(new InputStreamReader(System.in));
                    outputFile = br2.readLine();
                    
                    ReadLogFile logfile = new ReadLogFile();
                    
                    String[] nn = searchString.split(",");
                    for(int i = 0; i < nn.length; i++){
                                         List log = new ArrayList();    
                        log = logfile.readFile(inputFile,nn[i]);    
                        logfile.writeFile(log,outputFile);                    
                    }
                    System.out.println("Reading log file completed:|");
