每间隔5s打印一句hello
// time_ticker
package main
import (
"fmt"
"time"
)
func main() { fmt.Println("Hello World!")interval := 5 * time.Second
ticker := time.NewTicker(interval)
for i := 0; i < 6; i++ {/* ticker.C是一个通道，时间到了，通道就可读了 */
select {case <-ticker.C:
fmt.Println(<-ticker.C, "hello")
}
}
}
输出结果
Hello World!

定时器根据间隔时间写通道ticker.C, 所以可以监听通道ticker.C,一旦通道可读，就说明定时时间到了
