2.  1 No Comments with code
   It becomes hard to understand the  purpose of a method or the changes made to the repository
   2 Not choosing self explanatory names and the naming convention
   self explanatory names describe the purpose and by following naming convention our code works everywhere as in the case of java bean
   3 One function  performing more than one task 
   We lose the flexibility to combine the functions in desired way and also get the undesired side effect
   4 Not handling the runtime exception by using try catch
   it is better to display a meaningful message than the absurd technical exception as well as it continues the execution in most of the cases
   5 Not grouping the related classes and interfaces in  packages
   It adds to the complexity as the classes and interaces grow in number
