Create an entity class student

 Public classStudent {//namePrivateString name;//AgePrivateString age;//AddressPrivateString address; PublicString GetName () {returnname;} Public voidsetName (String name) { This. Name =name;} PublicString getage () {returnAge ;} Public voidsetage (String age) { This. Age =Age ;} PublicString getaddress () {returnaddress;} Public voidsetaddress (String address) { This. Address =address;} @Override PublicString toString () {return"Student [name=" + name + ", age=" + Age + ", address=" + address + "]";}}

Here's a way to convert the student object to JSON

 Public Static voidConvertobject () {Student stu=NewStudent (); Stu.setname ("JSON"); Stu.setage ("23"); Stu.setaddress ("Xicheng District, Beijing"); //1. Using JsonobjectJsonobject JSON =Jsonobject.fromobject (STU); //2. Using JsonarrayJsonarray array=Jsonarray.fromobject (STU); String Strjson=json.tostring (); String Strarray=array.tostring (); System.out.println ("Strjson:" +Strjson); System.out.println ("Strarray:" +Strarray); }

Jsonobject and Jsonarray methods print the results as follows:

strjson:{"Address": "Xicheng District, Beijing", "age": "All", "name": "JSON"}strarray:[{"address": "Xicheng, Beijing", "age": "All", "name": "JSON"}]

Jsonarray jsonarray=jsonarray.fromobject (ARRSTR); // get the first element of a JSON array Object o = jsonarray.get (0== (Student) Jsonobject.tobean (jsonobject,student.  Class);
