How to check if a Set is Not Empty in Go ?

Answer

To check if a Set is not empty in Go, you can use the len function or compare the length to zero.

✐ Examples

1 Check if Set is Not Empty Using len Function

In this example,

We define a non-empty set named mySet containing elements of a specific type.
We use the len function to get the number of elements in the set.
If the length is greater than zero, then the set is not empty; otherwise, it is empty.

Go Program

package main

import "fmt"

func main() {
    // Define non-empty set
    mySet := map[string]bool{"apple": true, "banana": true, "orange": true}

    // Check if set is not empty using len function
    if len(mySet) > 0 {
        fmt.Println("Set is not empty")
    } else {
        fmt.Println("Set is empty")
    }
}

Output

Set is not empty

2 Check if Set is Not Empty Using Length Comparison

In this example,

We define a non-empty set named mySet containing elements of a specific type.
We compare the length of the set to zero.
If the length is greater than zero, then the set is not empty; otherwise, it is empty.

Go Program

package main

import "fmt"

func main() {
    // Define non-empty set
    mySet := map[string]bool{"apple": true, "banana": true, "orange": true}

    // Check if set is not empty using length comparison
    if len(mySet) != 0 {
        fmt.Println("Set is not empty")
    } else {
        fmt.Println("Set is empty")
    }
}

Output

Set is not empty
