JSON array and list conversion related issues

I've used all of the following two methods.

Method One:

String jstr= "{' json ': ' Jsonvalue ', ' bool ': true, ' int ': 1, ' Double ': ' 20.5 '}";
Jsonobject Json=jsonobject.fromobject (JSTR);
Boolean Bool=json.getboolean ("bool");
int i=json.getint ("int");
Double d=json.getdouble ("double");
String value=json.getstring ("json");
System.out.println ("bool=" +string.valueof (BOOL) + "\tjson=" +value+ "\tint=" +i+ "\tdouble=" +d);

If you have a Bean object
Class user{
private String name;
Private String PSW;
Encapsulation Getter/setter omitted
}
String u= "{' name ': ' sail331x ', ' PSW ': ' 123456789 '}";
User user= (user) Jsonobject.tobean (jsonobject.fromobject (U), user.class);
You can do it.
To turn a user into a JSON object:
Jsonobject juser=jsonobject.fromobject (user);
String jstr=juser.tostring ();//This becomes a JSON string.

Method Two:

Declare a person entity class:

Package HB;

Import Java.util.Date;

public class Person {

String ID;
int age;
String name;
Date birthday;
Public String getId () {
return ID;
}
public void SetId (String id) {
This.id = ID;
}
public int getage () {
return age;
}
public void Setage (int.) {
This.age = age;
}
Public String GetName () {
return name;
}
public void SetName (String name) {
THIS.name = name;
}
Public Date Getbirthday () {
return birthday;
}
public void Setbirthday (Date birthday) {
This.birthday = Birthday;
}

}

Testing JSON data transformations

Package HB;

Import Java.util.Iterator;
Import java.util.List;

Import Org.junit.Test;

Import Net.sf.json.JSONArray;
Import Net.sf.json.JsonConfig;

public class Jsontolist {

public static void Main (string[] args) {
String json= "[{' Name ': ' Huangbiao ', ' age ': 15},{' name ': ' Liumei ', ' Age ': 14}]";
Jsonarray Jsonarray = Jsonarray.fromobject (JSON);
System.out.println (Jsonarray);
List List = (list) jsonarray.tocollection (Jsonarray, Person.class);
Iterator it = List.iterator ();
while (It.hasnext ()) {
Person P = (person) it.next ();
System.out.println (P.getage ());
}
}

@Test
public void JsonToList1 () {
String json= "[{' Name ': ' Huangbiao ', ' age ': 15},{' name ': ' Liumei ', ' Age ': 14}]";
Jsonarray Jsonarray = Jsonarray.fromobject (JSON);
System.out.println (Jsonarray);
List List = (list) jsonarray.tolist (Jsonarray, Person.class);
Iterator it = List.iterator ();
while (It.hasnext ()) {
Person P = (person) it.next ();
System.out.println (P.getage ());
}

}

@Test
public void JsonToList2 () {
String json= "[{' Name ': ' Huangbiao ', ' age ': 15},{' name ': ' Liumei ', ' Age ': 14}]";
Jsonarray Jsonarray = Jsonarray.fromobject (JSON);
System.out.println (Jsonarray);
System.out.println ("------------");
List List = (list) jsonarray.tolist (Jsonarray, new Person (), new Jsonconfig ());
Iterator it = List.iterator ();
while (It.hasnext ()) {
Person P = (person) it.next ();
System.out.println (P.getage ());
}

}

}

To convert a list object to a JSON string array:

Package HB;

Import java.util.LinkedList;
Import java.util.List;

Import Net.sf.json.JSONArray;

public class Listtojson {

public static void Main (string[] args) {
List List = new LinkedList ();
for (int i=0;i<3;i++) {
Person p = new person ();
P.setage (i);
P.setname ("name" +i);
List.add (P);
}
Jsonarray Jsonarray = jsonarray.fromobject (list);
System.out.println (Jsonarray);
}

}
