Apache spark - For loop

var l = List(34, 32, 132, 352)      // Scala List

l.foreach{i => 
    val data:DataFrame = DataContainer.getDataFrame(i) // get DataFrame
    val x = new MyClass(data)                     // initialize MyClass with new Object
    x.setSettings(...)
    x.calcSomething()
    x.saveResults()                               // writes the Results into another Dataframe that is saved to HDFS
}
