[GoLand] Timer Principle and difference between Timer and Ticker

A: The Timer

1.Timer Timer framework implementation

package main

import (
    "fmt"
    "time"
)

func main (a) {
    d := time.Duration(time.Second * 2)
    t := time.NewTimer(d)
    go func(a) {
        for {
            <- t.C
            fmt.Println("Timer task is working")
            t.Reset(time.Second * 2)}} ()for {
        fmt.Println("main is running:")
        time.Sleep(time.Duration(1 * time.Second))
    }
    defer t.Stop()
}

Ticker timer

1.Ticker timer framework implementation

package main

import (
    "fmt"
    "time"
)

func main (a) {
    d := time.Duration(time.Second * 2)
    t := time.NewTicker(d)
    go func(a) {
        for {
            <- t.C
            fmt.Println("Timer task is working")}} ()for {
        fmt.Println("main is running:")
        time.Sleep(time.Duration(1 * time.Second))
    }
    defer t.Stop()
}

3. Differences between Timer and Ticker

1. The Ticker does not need to Reset after the Timer expires. The Ticker performs the task processing function every time the Timer expires

// If the Timer does not use Reset, only one task is executed
package main

import (
    "fmt"
    "time"
)

func main (a) {
    d := time.Duration(time.Second * 2)
    t := time.NewTimer(d)
    go func(a) {
        for {
            <- t.C
            fmt.Println("Timer task is working")
            //t.Reset(time.Second * 2)
        }
    }()
    for {
        fmt.Println("main is running:")
        time.Sleep(time.Duration(1 * time.Second))
    }
    defer t.Stop()
}
