I am working through
Data Algorithms
book and
I am getting the following compilation error when trying to access Tuple2 members in Java:
I admit, that I am newish to Scala but the syntax looks right, per scala-lang so any help is appreciated. Thanks
_1 has private access in scala.Tuple2
_2 has private access in scala.Tuple2
The code snippet in question
List<Tuple2<String, Iterable<Tuple2<Integer,Integer>>>> output2 = groups.collect();
for(Tuple2<String, Iterable<Tuple2<Integer,Integer>>> t : output2){
Iterable<Tuple2<Integer,Integer>> list = t._2;
System.out.println(t._1);
for(Tuple2<Integer,Integer> t2 : list){
System.out.println(t2._1 + "," + t2._2);
