since it's a string, why not just add in the front end back like this?
String newstring =  "groupContacts: [" + yourInpuy + "]";

If you're manipulating this data programatically, you should probably be using a bean

Use Jackson to serialise it.
Add annotations for jsonroot and property annotations to getters.

Read up about it if you want to do it right.
Jackson is not the only option . There's others such as gson.

Being a developer means you should seek the best solutions that will be easy to maintain in future. Dont take shortcuts just because you can't be bothered to put the effort in.
