double minSupport = 0.9;
boolean pruneTreeOnInsert = true;
Map<Integer, Integer> oneItemsetCounts = FPGrowth.getOneItemsetCounts(transactions);
List<List<Integer> frequentItemsets = FPGrowth.findFrequentItemsetWithSuffix(
  FPGrowth.buildFPTree(transactions, oneItemsetCounts, pruneTreeOnInsert, minSupport),
  new ArrayList<Integer>(),
  ((int) minSupport * transactions.size())
);
