Try using Gson library

Gson g = new Gson();
Player p = g.fromJson(jsonString, Player.class)

You can also convert a Java object to JSON by using toJson() method as shown below

String str = g.toJson(p);

If you don't have a POJO representing the data, it can be done generally using JsonElement.

Demo

String input = "{Line:1,Direction:incoming,LocalUsername:xxx,AuthUsername:31223,PeerUsername:04232000113,Name:04232000113,Server:23424,Connectime:2189msec,Duration:0msec,DiscBy:Remote,Reason:cancelNormalcallclearing}";

Gson g = new Gson();
JsonElement root = g.fromJson(input, JsonElement.class);
String result = g.toJson(root);

System.out.println(result);

Output

{"Line":1,"Direction":"incoming","LocalUsername":"xxx","AuthUsername":31223,"PeerUsername":"04232000113","Name":"04232000113","Server":23424,"Connectime":"2189msec","Duration":"0msec","DiscBy":"Remote","Reason":"cancelNormalcallclearing"}

Since it isn't nested, simply add " around : and ,, and after { and before }:

s = s.replaceAll("(?<=[{:,])|(?=[:,}])", "\"");

See demo on regex101.com.
