scala for循环模糊匹配

object DI2 {
def main(args:Array[String]){
for(i<- 1 to 10){println(i)}
//变量名赋值
for(index@"link" <- List("af","hadoop","lik")){
println(index)
}
//查询set中值是hadooop的键值
for((language,"hadoop") <- Set("scala"->"spark","hadoop"->"java")){
println(language)
}
//过滤集合中 值是数字类型的
for((k,v:Int) <- List(("spark"->12),("hadoop"->"dfdf"))){
println(k+v)
}
}
}
