在 Scala 中迭代嵌套地图

Question

I am new to scala and need help in iterating a nested Map in scala .

This is what the Map looks like.

Map(EmpNo -> Map(name -> IntegerType, version -> 1), 
    Name -> Map(name -> StringType, version -> 1), 
    Salary -> Map(name -> DoubleType, version -> 1)) 

Answer 1

There you go.

yourMap foreach {
  case (key, innerMap) => innerMap foreach {
    case (innerKey, value) => // do something
  }
}
