How do I utilize a config file with my Java program?
google.com  15s
yahoo.com   10s

google.com=15
yahoo.com=10

final String path = "config.properties";

Properties prop = new Properties();

int pingTimeGoogle = prop.load(new FileInputStream(path)).getProperty("google.com");

final String path = "config.properties";

Properties props = new Properties().load(new FileInputStream(path));
Enumeration e = props.propertyNames();

while (e.hasMoreElements()) {
    String key = (String) e.nextElement();
    System.out.println(key + "=" + props.getProperty(key));
}

final String path = "config.properties";

Properties props = new Properties().load(new FileInputStream(path));

Map<String, Integer> pingUrlTimes = new HashMap<String, Integer>((Map) props);

Iterator iterator = pingUrlTimes.keySet().iterator(); // Get Iterator

while (iterator.hasNext()) {
    String key = (String) iterator.next();

    System.out.println(key + "=" +  pingUrlTimes.get(key) );
}

Map<String, Integer> pingUrlTimes = new HashMap<String, Integer>();
pingUrlTimes.put("google.com", 15);
pingUrlTimes.put("yahoo.com", 10);

int pingTime = pingUrlTimes.get("google.com");
