The easiest way to compare json strings is using JSONCompare from JSONAssert library. The advantage is, it's not limited to structure only and can compare values if you wish:

JSONCompareResult result = 
     JSONCompare.compareJSON(json1, json2, JSONCompareMode.STRICT);
System.out.println(result.toString());

which will output something like:

Expected: VALUE1
     got: VALUE2
 ; field1.field2
