Here is the code  and you can decide which  synchronized StringBuffer or  faster StringBuilder to use   Benchmark shows  StringBuilder is Faster   public class Main               int times   777              long t                                 StringBuffer sb   new StringBuffer                    t   System currentTimeMillis                    for  int i   times  i -- gt  0                          sb append                          getJSONFromStringBuffer String stringJSON                                     System out println System currentTimeMillis   - t                                                StringBuilder sb   new StringBuilder                    t   System currentTimeMillis                    for  int i   times  i -- gt  0                           getJSONFromStringBUilder String stringJSON                       sb append                                        System out println System currentTimeMillis   - t                             private String getJSONFromStringBUilder String stringJSONArray  throws JSONException                   return new StringBuffer                         new JSONArray stringJSONArray  getJSONObject 0  getString  phonetype                                append                                  append                         new JSONArray employeeID  getJSONObject 0  getString  cat                           toString                              private String getJSONFromStringBuffer String stringJSONArray  throws JSONException                   return new StringBuffer                         new JSONArray stringJSONArray  getJSONObject 0  getString  phonetype                                append                                  append                         new JSONArray employeeID  getJSONObject 0  getString  cat                           toString
