Scala 中断循环

一、采用 Scala 自带的函数，退出循环

 1 package com.atguigu.break
 2
 3 object TestBreak {
 4   import scala.util.control.Breaks
 5   def main(args: Array[String]): Unit = {
 6     Breaks.breakable(
 7       for (elem <- 1 to 10) {
 8         println(elem)
 9         if (elem == 5) Breaks.break()
10       }
11     )
12     println("正常结束循环")
13   }
14 }

二、 对 break 进行省略

 1 package com.atguigu.break
 2 import scala.util.control.Breaks._
 3 object TestBreak2 {
 4   def main(args: Array[String]): Unit = {
 5     breakable {
 6       for (elem <- 1 to 10) {
 7         println(elem)
 8         if (elem == 5) break
 9       }
10     }
11     println("正常结束循环")
12   }
13 }
