Interface vs Abstract Class in Java: What's the Difference?

The main difference between package and interface is that a package is a collection of related classes and interfaces while an interface is a collection of fields and abstract methods.

In other words, to write Go well, it's important to understand its properties and idioms. It's also important to know the established conventions for programming in Go, such as naming, formatting, program construction, and so on, so that programs you write will be easy for other Go programmers to understand. This document gives tips for writing clear, idiomatic Go code. It augments the language specification , the Tour of Go , and How to Write Go Code , all of which you should read first.
