Parsing mailing address in Java

Recently came across a problem to parse postal address String using Java, did some research here are some findings.

String s = "60 Strawberry Hill Ave Stamford CT 06901"
Required Result
Street = Strawberry Hill Ave
City = Stamford
Number = 60
zip = 06901
state = CT
You can use JGeocoder

public static void main(String[] args) {
Map<AddressComponent, String> parsedAddr  =     AddressParser.parseAddress("Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043");
Map<AddressComponent, String> normalizedAddr  = AddressStandardizer.normalizeParsedAddress(parsedAddr);
Output will be:

{street=Amphitheatre, city=Mountain View, number=1600, zip=94043, state=CA, name=Google Inc, type=Parkway}
{street=AMPHITHEATRE, city=MOUNTAIN VIEW, number=1600, zip=94043, state=CA, name=GOOGLE INC, type=PKWY}

There is another library International Address Parser , it provides a trial version. It supports country as well.

AddressParser addressParser = AddressParser.getInstance();
AddressStandardizer standardizer = AddressStandardizer.getInstance();  
AddressFormater formater = AddressFormater.getInstance();
String rawAddress = "101 Avenue des Champs-Elysées 75008 Paris";

//you can try to detect the country
CountryDetector detector = CountryDetector.getInstance();
String countryCode = detector.getCountryCode("7580 Commerce Center Dr ALABAMA");
System.out.println("detected country=" + countryCode);

Also, please check Implemented Countries

Hope you find this helpful

Cheers !!

Drools - An overview

For Java based applications the most challenging part has always been the business logic maintenance, and pick any applications which you find complex and if we ask ourself how complex it would be moving forward, the answer will always be nX times.

What do we do ? Drools comes for Rescue as a Rule Engine.

Drools provides mechanism:

a. To write business logic in simple english language
b. Easy to maintain and very simple to extend
c. Reusability of logic by defining keywords in a DSL file and using them in DSLR file.

But be careful nothing comes free, everything takes cost in terms of memory and time space.

Use Drools if you really have :

a. Business logic which you think is getting cluttered with multiple if conditions because of variety of scenarios
b. You will have growing demand of increase in the complexity
c. The business logic changes would be frequent (1 - 2 times a year would also be frequent)
d. Your server's have enough of memory as it is a memory hungary tool, it provi…

Java 8 streams performance on mathematical calculations

Java 8 Streams API supports many parallel operations to process the data, it abstracts low level multithreading logic. To test performance did following simple test to calculate factorial of first X number starting with N.

Following program calculates factorial of first 1000 numbers.

package; import java.math.BigInteger; import java.time.Duration; import java.time.Instant; import java.util.ArrayList; import java.util.List; publicclassMathCalculation { publicstaticvoid main(String[] args) { List<Runnable> runnables = generateRunnables(1, 1000); Instant start=; // Comment one of the lines below to test parallel or sequential streams runnables.parallelStream().forEach(r ->; // ->; Instant end =; System.out.println("Calculated in "+ Duration.between(start, end)); } privatestaticvoid factorial(int number) { int i; BigInteger fact = BigInteger.valueOf(1); for (i =1; i <= numb…

MQTT : Android step by step guide using Eclipse Paho

For MQTT integration, recently explored Paho Android project, very simple to use, here are the steps:

Intialize a client, set required options and connect.

    MqttAndroidClient mqttClient = new MqttAndroidClient(BaseApplication.getAppContext(), broker, MQTT_CLIENT_ID);
    //Set call back class
    mqttClient.setCallback(new MqttCallbackHandler(BaseApplication.getAppContext()));
    MqttConnectOptions connOpts = new MqttConnectOptions();
    IMqttToken token = mqttClient.connect(connOpts);

Subscribe to a topic.

    token.setActionCallback(new IMqttActionListener() {
      public void onSuccess(IMqttToken arg0) {
           mqttClient.subscribe("TOPIC_NAME" + userId, 2, null, new IMqttActionListener() {
                public void onSuccess(IMqttToken asyncActionToken) {
                    Log.d(LOG_TAG, "Successfully subscribed to topic.");
