Java ArrayList to JSON object go JSON

The introduction of related packages, the package used here is net.sf.json-lib:json-lib:2.4, but the introduction of a bit of a pit, the package has two versions, jdk1.5 and jdk1.4, the introduction of the time to add the corresponding JDK version number, or not to introduce success.

Gradle is used here, so add a line in the dependencies

Compile "net.sf.json-lib:json-lib:2.4:jdk15"

If you write compile "net.sf.json-lib:json-lib:2.4", then you cannot introduce success.

The following code shows how to turn ArrayList into JSON or how to turn a Java object into JSON

public class Javaobject{private String Name;public string GetName () {return name;} public void SetName (String name) {this.name = name;}} @Testpublic void Arraylist2jsonandobject2json () {Javaobject javaobjecta = new Javaobject (); Javaobjecta.setname ("A"); Javaobject JAVAOBJECTB = new Javaobject (); Javaobjectb.setname ("B"); list<javaobject> javaobjectlist = new arraylist<> (); Javaobjectlist.add (javaobjecta); javaObjectList.add (JAVAOBJECTB); System.out.println (Jsonobject.fromobject (javaobjecta)); System.out.println (Jsonarray.fromobject (Javaobjectlist));}

The core approach is

System.out.println (Jsonobject.fromobject (javaobjecta)); System.out.println (Jsonarray.fromobject (javaobjectlist));

The result of the output is

{"Name": "A"} [{"Name": "A"},{"name": "B"}]
