JSON basic usage

1 The data class (gets to be converted to JSON)

Package org.data;

Import java.util.ArrayList;
Import Java.util.HashMap;
Import java.util.List;
Import Java.util.Map;

public class Data {

Public list<string>getList (){
list<string> list = new arraylist<string> ();
List.add ("Xixi");
List.add ("haha");
List.add ("SB");
return list;
}
Public map<string, string>Getmap (){
map<string, string> map = new hashmap<string, string> ();
Map.put ("name", "Xiao Bo");
Map.put ("Sex", "male");
Map.put ("Age", "Infinity");
Map.put ("The Other Half", "no");
Map.put ("First Love", "ran");
return map;
}
Public boolean[]GetArray (){
boolean[] Boolarray = new boolean[] {true, false, true};
return boolarray;
}
}
2Bean (JavaBean can also be converted to JSON)Note: To add getter and setter

Package org.data;

public class Jsonbean {
private String name;
Private String sex;
Private String age;
Public String GetName () {
return name;
}
public void SetName (String name) {
THIS.name = name;
}
Public String Getsex () {
return sex;
}
public void Setsex (String sex) {
This.sex = sex;
}
Public String Getage () {
return age;
}
public void Setage (String age) {
This.age = age;
}
Public Jsonbean (String a,string B, string c) {
This.setname (a);
This.setsex (b);
This.setage (b);
}
}

3 Test class

Package org.data;

Import java.util.List;
Import Java.util.Map;

Import Net.sf.json.JSONArray;
Import Net.sf.json.JSONObject;

public class Parsejsontest {

public static void Main (string[] args) {
TODO auto-generated Method Stub
Data data=new data ();
List list=data.getlist ();
Map Map=data.getmap ();
Boolean[] B=data.getarray ();


Jsonarray jsonarrayfromlist = jsonarray.fromobject (list);
Jsonobject Jsonobjectfrommap = jsonobject.fromobject (map);
Jsonarray Jsonarrayfromarray = Jsonarray.fromobject (b);
System.out.println (jsonarrayfromlist);
System.out.println (JSONOBJECTFROMMAP);
System.out.println (Jsonarrayfromarray);


Jsonarray jsonarrayfromstring= jsonarray.fromobject ("[' json ', ' is ', ' easy ']");
System.out.println (jsonarrayfromstring);


Jsonobject Jsonobjectfrombean = jsonobject.fromobject (New Jsonbean ("Xiao Bo", "Male", "at"));
System.out.println (Jsonobjectfrombean);

}

}
