Go language types and interfaces

This is a creation in Article, where the information may have evolved or changed.

In the go language, as long as a type implements an interface containing a method, we can assume that the type implements the interface, the following is an example of a simple type and interface in the go language.

Package Mainimport (    "FMT")//define an interface to implement the Run method type Irun interface {    run ()}//define an adult type of man struct {}// Define a child type a kid struct {}//implements the Run method for adults, and essentially implements the Irun interface func (M *man) run () {FMT) for adults    . PRINTLN ("Adult Running")}//for the child to implement the Run method, the essence is to implement the child Irun interface func (k *kid) run () {    fmt. PRINTLN ("Child Running")}func main () {    var krun irun = new (Kid)    Krun.run ()    var mrun irun = new (man)    Mrun.run ()}

The kid's running.
The adults are running.
