Kotlin Break Statement

Kotlin provides the break statement to implement the middle-existing control logic. The break statement causes the immediate exit from the body of the loop.

Kotlin Continue Statement

The continue statement is similar to the break statement. When continue statement is executed, it stops the current iteration of the loop and continue with the next iteration of the loop.

The statement in kotlin is marked with a label. The label has the form of an identifier followed by the @ sign.

Example of break continue

fun main(args : Array<String>)  { 
    loop@ for (n in 1..100) {
        println("$n")
        if (n == 10)
            break@loop
    }
    val l2 = listOf(10, 11, 12, 13)
    loop@ for (m in l2) {
        if(m == 11) {
            println("This is if block")
            break@loop
        } else {
            println("This is else block")
            continue@loop
        }
    }
}

Output

Kotlin Return Statement

The return expression returns some values from the nearest enclosing function.

Example

fun main(args : Array<String>)  { 
    val c = city()
    println("City = $c")
}
fun city() : String {
    return "Pune"
}

Output

City = Pune
