Scala – Break Statement with Loops

Here, we will demonstrate the break statement in the while and do-while loop to terminate the loop during its execution based on the specific condition.

Scala code to demonstrate the example of break statement in while and do-while loops

The source code to demonstrate the break statement in the while and do-while loop is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

In the all below program, we used an object-oriented approach to create the program. We created an object Sample. We imported the scala.util.control.Breaks._ package to use the break statement.

break statement with while loop

// Scala program to demonstrate the "break" statement 
// in a "while" loop

// Importing the package
import scala.util.control.Breaks._

object Sample {  
    def main(args: Array[String]): Unit = {
        // Variable declaration and initialization
        var cnt: Int = 1

        // Using the breakable block to allow a break
        breakable {
            while (cnt <= 5) {
                // Printing the current value of cnt
                print(s"$cnt ")

                // Incrementing cnt
                cnt += 1

                // Breaking the loop when cnt equals 3
                if (cnt == 3)
                    break
            }
        }

        // Printing a new line for better output formatting
        println()
    }
}

Output

1 2 

Explanation

Here, we created an integer variable cnt initialized with 0. We created a breakable block to use the break statement.

In the while loop, we print the value of the cnt variable. We terminate the loop using the break statement when the value of the cnt variable reaches 3.

break statement with do-while loop

// Scala program to demonstrate the "break" statement 
// in a "do-while" loop

// Importing the package
import scala.util.control.Breaks._

object Sample {  
    def main(args: Array[String]): Unit = {
        // Variable declaration and initialization
        var cnt: Int = 1

        // Using a breakable block to enable breaking the loop
        breakable {
            do {
                // Printing the current value of cnt
                print(s"$cnt ")

                // Incrementing cnt
                cnt += 1

                // Breaking the loop when cnt equals 3
                if (cnt == 3) break
            } while (cnt <= 5)
        }

        // Printing a new line for better output formatting
        println()
    }
}

Output

1 2
