Loading configuration parameters from textfile into a program

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Properties;



public class Main {
    
    Properties config;
    
    /**
     * Loads configuration parameters from a textfile and print them out.
     */
    public void loadConfigFile() {

        //Load configuration file
        String filename = "conf/systemconfig.txt";
        config = new Properties();

        try {

            config.load(new FileInputStream(filename));

        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
            return;
        } catch (IOException ex) {
            ex.printStackTrace();
            return;
        }
        
         
        //Print out the configuration parameters
        Enumeration en = config.keys();
        
        System.out.println("********** System configuration **********");
        while (en.hasMoreElements()) {
            
            String key = (String) en.nextElement();
            System.out.println(key + " => " + config.get(key));
            
        }
    }
    /**
     * Starts the program
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().loadConfigFile();
    }
}


 

This is the output after printing out the loaded configuration parameters:


********** System configuration **********
parameter2 => value2
parameter1 => value1
