The source code to check the channel is empty or not is given below. The given program is compiled and executed successfully.
// Golang program to check the channel is
// empty or not
package main
import "fmt"
func main() {
//Create a bidirection channel with capacity 2.
msg1 := make(chan string, 2)
if len(msg1) == 0 {
fmt.Println("Channel msg1 is empty")
} else {
fmt.Println("Channel msg1 is not empty")
}
//Create a bidirection channel with capacity 3.
msg2 := make(chan string, 3)
msg2 <- "Hello"
msg2 <- "Hiiii"
if len(msg2) == 0 {
fmt.Println("Channel msg2 is empty")
} else {
fmt.Println("Channel msg2 is not empty")
}
}
Output:
Channel msg1 is empty
Channel msg2 is not empty
Explanation:
In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package to formatting related functions.
In the main() function, we created two bidirectional channels and then we checked the channel is empty or not and print the appropriate message on the console screen.
