vonkonyoung commented 3 years ago

i found the code that cause the problem like this: ![Uploading image.png…]() code: package base

object BreakableTest {

def main(args: Array[String]): Unit = { import scala.util.control.Breaks._ breakable { var n = 10 for(c <- "Hello World") { if(n == 5) break; print(c) n -= 1 } }

}

} and why? who can tell me the reason
