Scala 不支持 break 和 continue 关键字

scala.util.control.Breaks

注意 breakable 代码块的位置 ，在循环内，就是continue，在循环外就是break


import scala.util.control._

object BreakDemo {
   def main(args: Array[String]) {
      var a = 0;
      val numList = List(1,2,3,4,5);
      // break
      val loop = new Breaks;
      loop.breakable {
         for( a <- numList){
            if( a == 3 ){
               loop.break;
            }
            println( "Value of a: " + a );
         }
      }
      println( "After the loop1" );
      // continue
      val loopForContinue = new Breaks;
      for( a <- numList){
            loopForContinue.breakable {
              if( a == 3 ){
                loopForContinue.break;
              }
              println( "Value of a: " + a ); 
            }
         }
       println( "After the loop2" );
   }
}
