go语言中select与switch的区别

package main

import (

"fmt"

)

func main() {

key := 10

switch key {

case 7:

fmt.Println("7")

case 10:

fmt.Println("10")

default:

fmt.Println("default")

}

ch := make(chan int, 1)

ch <- 10

select {

case <-ch:

fmt.Println("receive")

default:

fmt.Println("default")

}

}
