Hi Faisal, thanks for the PR. Would you mind updating these equals() implementations to use Objects.equals(.., ...) instead? Also, I prefer not to see if blocks without braces.

I try to follow https://google.github.io/styleguide/javaguide.html except we use 4 space tabs. The point of note here is https://google.github.io/styleguide/javaguide.html#s4.1.1-braces-always-used
