Using GSON to Parse JSON in Java

The following is a video and the program to understand the how JSON can be Parsed  in Java using Gson library from Google.

Here is the entire program:
  1. package json;
  3. import com.google.gson.Gson;
  4. import com.google.gson.JsonElement;
  6. public class JSONParsing {
  8. public static void main(String[] args) {
  9. Gson gson = new com.google.gson.Gson();
  10. String json = "{\"city\": \"NewYork\", \"zip\": \"l2345\", \"timeZone\":\"EST\", \"Country\": \"USA\", \"population\":632541,"
  11. + " \"month\": September,\"year\":\"2015\"}";
  13. System.out.println("Original Object:\n"+json+"\n");
  14. com.google.gson.JsonObject result = gson.fromJson(json,
  15. JsonElement.class).getAsJsonObject();
  17. System.out.println("JsonObject Object:\n"+result.toString());
  18. System.out.println();
  20. System.out.println("\nGetting specific element:zip:"
  21. + result.get("zip"));
  23. City city = new City();
  24. city.setName(result.get("city").getAsString());
  25. city.setPopulation(result.get("population").getAsLong());
  27. System.out.println("\n"+city.toString());
  29. }
  31. }
  33. class City {
  34. private String name;
  35. private Long population;
  36. public String getName() {
  37. return name;
  38. }
  39. public void setName(String name) {
  40. this.name = name;
  41. }
  42. public Long getPopulation() {
  43. return population;
  44. }
  45. public void setPopulation(Long population) {
  46. this.population = population;
  47. }
  48. @Override
  49. public String toString() {
  50. return "City [name=" + name + ", population=" + population + "]";
  51. }
  54. }

Java Interview : Threads

Java came up with multi threading long time back, still the kind of response it invokes when this topic raises its head during interviews is not very encouraging. If you have attended an java interview, a couple of suppose to be very smart guys also know as lead developers will shower you with questions on multi threading, grilling you down to make sure what you are talking about, even asking you to write fork-join snippets to solve hadoop use cases. But if you are hired and you write a piece code using executor framework, you will be seen with suspicion generally reserved for people with casual shoes at cocktail parties. So here is post to start out thinking about threads. So a path of execution in java is known as a thread, appropriately an instance of Thread class. The main method runs in its own thread and starts up the program execution. If you implement the Runnable interface, you can run in a thread of you own. The Runnable interface has a run() method you implement your...

Spring Framework Interview Notes : Part Two Wiring

Image
The Spring container is the guy responsible to get the train moving when working with the Spring framework.  The dependency magic gets the things working by somehow getting all the stuff up and running. Now somehow we need to indicate to the spring container as to where and how to “wire” these beans. Remember these beans are also known as components. Components combine to form the structure and thus make the functionality. The concept of component scanning or component finding comes into the picture, literally searching the applications to find the beans required to create these beans. @ComponentScan is the annotation used by giving the the base packages where these components are defined using annotation or xml . Spring Framework Interview Wiring You can also use Autowiring with its attributes, which finds the beans by-name or by-type and injects them appropriately. @Component, @ComponentScan, @Autowired, @Named,  @Bean  with requires and quali...
