JAVA uses Gson to parse json data, instance, and gsonjson

Encapsulation class Attribute:

public class Attribute {private int id;private String name;private int age;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}}

Another encapsulation class GsonDataAnalysis:

public class GsonDataAnalysis {private List<Attribute> list;public List<Attribute> getList() {return list;}public void setList(List<Attribute> list) {this.list = list;}}

Main method of the test class:

/*** Gson parses json data * @ author ForeverLover * @ version 2015-04-19 */public class GsonTest {public static void main (String [] args) {String sTotalString = "{\" list \ ": [" + "{\" id \ ": \" 1 \ ", \" name \": \ "Tom \", \ "age \": \ "12 \"}, "+" {\ "id \": \ "2 \", \ "name \": \ "Marry \", \ "age \": \ "18 \"} "+"]} "; Gson gson = new Gson (); gsonDataAnalysis gda = gson. fromJson (sTotalString, GsonDataAnalysis. class); for (int I = 0; I <gda. getList (). size (); I ++) {System. out. print ("ID:" + gda. getList (). get (I ). getId () + ""); System. out. print ("Last Name:" + gda. getList (). get (I ). getName () + ""); System. out. println ("Age:" + gda. getList (). get (I ). getAge ());}}}

Note: when using the Gson class, add the Gson. jar package to the project.
