Scala中的continue和break,即breakable和break

在Scala中要想实现对循环的控制，即continue和break.

Scala中有一个Breaks类（在包scala.util.control中）

• break

// D:\Scala\test\Breaks.scala
import scala.util.control.Breaks._
val array = Array(1,3,10,5,4)
breakable{
for (i<-array){
    if(i>5) break//跳出breakable,终止for循环
println(i)
    }
}

D:\Scala\test>scala Breaks.scala

• continue

// D:\Scala\test\Breaks1.scala
import scala.util.control.Breaks._
val array = Array(1,3,10,5,4)
for (i<-array){
    breakable{
        if(i>5)break
println(i)
        }
}
