break在scala和java中的区别解析

import scala.util.control.Breaks

object breakDemo {
 //break在scala中的使用
 def main(args: Array[String]): Unit = {
  //创建Breaks对象
  var a = 0
  val numList = List(1, 2, 3, 4, 5, 6, 7, 8, 9);
  val loop = new Breaks;
  //在breakable中的循环
  loop.breakable {
   for (a <- numList) {
    println("Value of a: " + a)
    if (a == 4) {
     loop.break();
    }
   }
  }
  println("After the loop")
 }
}

Value of a: 1
Value of a: 2
Value of a: 3
Value of a: 4
After the loop

import java.util.ArrayList;

public class breakDemo {
  public static void main(String[] args) {
    //break在java中的用法
    int[]a = new int[9];
    a[0]=1;
    a[1]=2;
    a[2]=3;
    a[3]=4;
    a[4]=5;
    a[5]=6;
    a[6]=7;
    a[7]=8;
    a[8]=9;
    for (int i = 0;i<a.length;i++){
      System.out.println(a[i]);
      if (a[i]==4){
        break;
      }
    }
  }
}
