make sure we are not violating DRY

hope no other library already exists for these things, like in apache commons , guava, jodatime, lombok, etc.

if there are better use them, or contribute to them instead.

i have not checked every method but several basic methods should already be available in other libraries, such as CollectionHelper.isEmpty, but other methods may have different implementation, such as CollectionHelper.addToList vs Apache's CollectionUtils,addAll

Creating our own libraries gives us more control to define what a particular method should do or return, imo. Should we wrap other libraries and base similar/same methods on top of those libraries? Although this will result in added dependency to those libraries for the clients that use this library.

what is the cons of having our own library?

[bunthatcodes]

imo we have more control over the implementation and our developers would be able to get all helpers in one place and not have to deal with multiple libraries from multiple 3rd parties (figuring out which library is located in which 3rd party class)
