Java Create and read JSON

I use Org.json to construct and parse JSON in Java, and the attachment is the corresponding Org.json.jar.

Here are two functions, one to create JSON, and one to construct the JSON from the text and parse it.

To create a JSON:

//construct JSON and output it PublicString Jsontest ()throwsjsonexception{jsonobject JSON=NewJsonobject (); Jsonarray jsonmembers=NewJsonarray (); Jsonobject Member1=NewJsonobject (); Member1.put ("LoginName", "Zhangfan"); Member1.put ("Password", "Userpass"); Member1.put ("Email", "[email protected]"); Member1.put ("Sign_date", "2007-06-12");        Jsonmembers.put (Member1); Jsonobject Member2=NewJsonobject (); Member2.put ("LoginName", "ZF"); Member2.put ("Password", "Userpass"); Member2.put ("Email", "[email protected]"); Member2.put ("Sign_date", "2008-07-16");      Jsonmembers.put (MEMBER2); Json.put ("Users", jsonmembers); returnjson.tostring (); }

Parsing JSON:

//construct JSON from String and resolve it. PublicString JsonTest2 ()throwsjsonexception{String jsonstring= "{\" users\ ": [{\" loginname\ ": \" zhangfan\ ", \" password\ ": \" Userpass\ ", \" email\ ": \" [Email protected]\ "},{\" Loginname\ ": \" zf\ ", \" password\ ": \" Userpass\ ", \" email\ ": \" [Email protected]\ "}]}"; Jsonobject JSON=NewJsonobject (jsonstring); Jsonarray Jsonarray=json.getjsonarray ("Users"); String Loginnames= "LoginName list:";  for(intI=0;i<jsonarray.length (); i++) {Jsonobject user=(jsonobject) jsonarray.get (i); String UserName= (String) user.get ("LoginName"); if(I==jsonarray.length ()-1) {Loginnames+=UserName; }Else{loginnames+=username+ ","; }    }    returnLoginnames;}

Jar Package: Json.jar
