How to replace a triple for loop using the Java 8 streams API

Question

I’m trying to navigate over 3 lists (nested triple for loop) and set some values based on a match. Below is a class representation and also the triple for loops I’m iterating over and doing the setting based on a match.

My question is, how would I replace the loops included below, using the streams API?

I’m new to Java and trying to wrap my head around Java 8 features. Any help would be greatly appreciated. thank you and have a wonderful day!

Listed below are the classes involved and the loops which I want to replace with the Java 8 streams API:

CLASSES:

class B {
  Long Id;
  Long x;
  String y;
  Long z;
}

class A {
  private  Long Id;
  private  List<B> bList;
}

class C {
  private  Long Id;
  private  List<Long> bIds;
  private  String y;
  private Long z;
}

NESTED FOR LOOPS:

  void f(List<A> aList, List<C> cList) {
    for(A a : aList) {
      List<B> bList= a.getBList();
      for(B b : bList) {
        for(C c : cList) {
          if(a.getId().equals(c.getId()) && c.getBIds().contains(b.getId())) {
            b.setZ(c.getZ());
            b.setY(c.getY());
          }
        }
      }
    }
  }
