How to check if an Array is Not Empty in Go ?

Answer

In Go, you can use the len function to get the length of an array and check if it's not empty.

✐ Examples

1 Check if Given Array with Elements is Not Empty

In this example,

We create an array named numbers with some elements.
We check if the array is not empty by getting its length using the len function and comparing it with 0, and store the result in the variable notEmpty.
Finally, we print whether the array is not empty or not.

Go Program

package main
import "fmt"
func main() {
    numbers := []int{1, 2, 3}
    notEmpty := len(numbers) != 0
    fmt.Printf("Array is not empty: %t\n", notEmpty)
}

Output

Array is not empty: true

2 Check if Empty Array is Not Empty

In this example,

We create an empty array named emptyArray.
We check if the array is not empty by getting its length using the len function and comparing it with 0, and store the result in the variable notEmpty.
Finally, we print whether the array is not empty or not.

Go Program

package main
import "fmt"
func main() {
    emptyArray := []int{}
    notEmpty := len(emptyArray) != 0
    fmt.Printf("Array is not empty: %t\n", notEmpty)
}

Output

Array is not empty: false
