Java – jump to the beginning of the for loop in a Scala program

In the for loop in my Scala code, I want to jump to the beginning of the loop. If the specific condition is true, the following statement will not be executed In Java, I can use 'continue' to do this But 'continue' doesn't seem to work in scala

Please help. Thank you

Solution

If you are using Scala 2.7, from http://www.scala-lang.org/node/257 start

If you are using Scala 2.8

import util.control.Breaks._
// for continue,write this somewhere in your program
val continue = new Breaks
/* use like */
Breaks.breakable {
  for (i <- 1 to 10)
  continue.breakable { if (i % 2 == 0) continue.break; println(i); if (i == 7) Breaks.break }
}

Note that the usual need to interrupt and continue means that you don't have the functionality Scala wants
