Is there any difference between switch
and select
in Go,
apart from the fact that one takes an argument and the other not?
Go中的switch和select有什么区别?

A
select
is only used with channels. ExampleA
switch
is used with concrete types. ExampleA
select
will choose multiple valid options at random, while aswitch
will go in sequence (and would require a fallthrough to match multiple.)Note that a switch can also go over types for interfaces when used with the keyword
.(type)
var a interface{} a = 5 switch a.(type) { case int: fmt.Println("an int.") case int32: fmt.Println("an int32.") } // in this case it will print "an int."
