Q:

Scala program to execute do-while loop at least 1 time on false condition

belongs to collection: Scala Looping Programs

Here, we will execute the body of the do-while loop at least once, even condition is false. Because the do-while loop is an exit control loop, here loop condition is checked after the body of the loop.

Program/Source Code:

The source code to execute the do-while loop at least 1 time on a false condition is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to execute "do-while" loop 
// at least 1 time on false condition

object Sample {  
    def main(args: Array[String]) {  
        do
        {
            println("Hello World");
        }while(false)
    }
}  

Output:

Hello World

Explanation:

In the above program, we used an object-oriented approach to create the program. We created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we used false in loop condition, but do-while is exit control loop, that why it will execute at least once and print "Hello World" message on the console screen.
