package main

import (

“fmt”

” os”

)

func main() {

file, err := os.Open(“./src/ main/test.txt”)

if err != nil {

fmt.Println(“open error “, err)

}

defer file.Close()

fmt.Println(file)

}

defer file.Close() will have a gray prompt in goland, saying Unhandled error. An error may occur during close. How should I deal with this error?
