Why many Gophers eschew Java

If you like design patterns, use Java, not Go.

Let's think about where this thinking comes from. Java (as well as C++) tends to focus on type hierarchies and type taxonomies.

Take the ObjectRetrievalFailureException class from the Spring Framework for example:

This looks far too complicated and over-abstracted, right?

Unlike Java, Go is designed to be a pragmatic language where we won't get lost in infinite levels of inheritance and type hierarchies.

When we implement a solution in a language that places so much emphasis on a type hierarchy, levels of abstractions, and class inheritance, our code refactorings tend to be much more time-consuming. It's best to get the design right before we begin coding. Leveraging design patterns can save a lot of time when implementing Java solutions.

Inheritance creates a high level of coupling in object-oriented programming. In the preceding example, a change in the DataAccessException class could cause unwanted side effects in every...
