errors.New() Function in Golang with Examples

Last Updated : 03 May, 2020

Errors package in Golang is used to implement the functions to manipulate the errors. errors.New()function returns an error that formats like given text. Each call to New returns distinct error value indeed in the event that the content is indistinguishable.

Syntax:

func New(text string) error

It returns an error.

Example 1:

// Golang program to illustrate 
// the errors.new() function  
package main 
  
import ( 
    "errors"
    "fmt"
) 
// Main function 
func main() { 
    err := errors.New("Sample Error") 
    if err != nil { 
        fmt.Print(err) 
    } 
} 

Output:

Sample Error

Example 2:

// Golang program to illustrate 
// the errors.new() function 
package main 
  
import ( 
    "errors"
    "fmt"
) 
  
// Main function 
func main() { 
    err := errors.New("It Says Error!") 
    if err != nil { 
        fmt.Print(err) 
    } 
} 

Output:

It Says Error!
