line 170 172 174 182 184 185 221 236
   analysis and explanation:
   The return value from a method is dereferenced without a null check, and the 
return value of that method is one that should generally be checked for null. 
This may lead to a NullPointerException when the code is executed.
   
   
   ### Describe the solution you'd like
   
   add NPE exception check.
   
   ### Are you willing to submit PR?
   
   - [ ] Yes I am willing to submit a PR!
