15. News List list = List.of(a, b, c); Set set = Set.of(d, e, f, g); Map map = Map.of(k1, V1);//not collection List list = #[ 1, 2, 3 ];

16. Money Api Take care of money to you :) Formating Rounding Exchange Rate

17. Money Api CurrencyUnit euro = MonetaryCurrencies.getCurrency("EUR"); MonetaryAmount money = Money.of(120, euro); NumberValue number = money.getNumber(); BigDecimal value = number.numberValue(BigDecimal.class);

18. Money Api CurrencyUnit dollar = MonetaryCurrencies.getCurrency(Locale.US); MonetaryAmount m = Money.of(120, dollar); NumberValue number = m.getNumber(); BigDecimal value = number.numberValue(BigDecimal.class);

19. Money Api MonetaryAmountFormat format = MonetaryFormats.getAmountFormat(Locale.US); String text = format.format(m);//12,50 USD format = MonetaryFormats.getAmountFormat(AmountFormatQueryBuild er.create(Locale.US).set(CurrencyStyle.SYMBOL).build()); String text = format.format(m);//$123,456.56

20. Money Api MonetaryAmount noMoney = Money.of(0, euro); MonetaryAmount m1 = Money.of(10, euro); MonetaryAmount m2 = Money.of(30, euro); MonetaryAmount m3 = Money.of(40, euro); List moneys = Arrays.asList(m1, m2, m3); MonetaryAmount sum = moneys.stream().reduce(MonetaryFunctions.sum()).orElse(noM oney);

21. Welcome Lambda List justDollar = moneys.stream() .filter((MonetaryFunctions.isCurrency(DOLLAR))) .collect(Collectors.toList()); List notEuro = moneys.stream().filter((MonetaryFunctions.isNotCurrenc y(EURO))).collect(Collectors.toList());

22. Welcome Lambda MonetaryFunctions.isCurrency(DOLLAR).and(Monetary Functions.isBetween(min, max))); MonetaryFunctions.containsCurrencies(EURO, DOLLAR)).or(MonetaryFunctions.isGreaterThan(money )));

23.

28. Exchange Rate MonetaryAmount m1 = Money.of(10, euro); MonetaryAmount m2 = Money.of(30, dollar); m1.add(m2); throw MonetaryException (Currency mismatch...

29. Exchange Rate ExchangeRateProvider provider = MonetaryConversions.getExchangeRateProvider("ECB"); MonetaryAmount d2e = provider.getCurrencyConversion(euro).apply(mDollar);

30. Exchange Rate ExchangeRateProvider provider = MonetaryConversions.getExchangeRateProvider("IMF"); MonetaryAmount d2e = provider.getCurrencyConversion(euro).apply(mDollar);

31. Exchange Rate List orderCurrencyValue = moneys.stream().sorted(MonetaryFunctions.sortExcha nge(provider).collect(Collectors.toList()); 9 BRL 8 USD 7 EUR Because: 1 USD = 2.4203 BRL 1 USD = 2.4203 BRL 1 USD = 0.79 EUR 7 EUR 9 BRL 8 USD

33. Exchange Rate MonetarySummaryStatistics summary = getCurrencies().stream().collect(MonetaryFunctions.sum marizingMonetary(DOLLAR, provider));

34. Measurement API Work with Measure Standardize measure unit Format Operations (convert, add, subtract)

35. Measurement API QuantityFactory massFactory = QuantityFactoryProvider.getQuantityFactory(Mass.class); Quantity tenKilogram = massFactory.create(10, SI.KILOGRAM);

36. Measurement API QuantityFactory timeFactory = QuantityFactory.getInstance(Time.class); Quantity m1 = timeFactory.create(40, MINUTE); Quantity m2 = timeFactory.create(20, MINUTE); Quantity h1 = m1.add(m2).to(HOUR); //1 hour

37. Measurement API QuantityFactory timeFactory = QuantityFactory.getInstance(Time.class); Quantity m1 = timeFactory.create(1, DAY); Quantity m2 = timeFactory.create(12, HOUR); Quantity result = m1.add(m2); //1.5 day

38. Measurement API Quantity minutes = Quantities.getQuantity(15, SI.MINUTE); Quantity hours = Quantities.getQuantity(18, SI.HOUR); Quantity day = Quantities.getQuantity(1, SI.DAY); Quantity seconds = Quantities.getQuantity(100, SI.SECOND); List> times = new ArrayList(); times.addAll(Arrays.asList(minutes, hours, day, seconds));

39. Measurement API List> sortNaturalList = times.stream() .sorted(QuantityFunctions.sortNatural()) .collect(Collectors.toList()); seconds - 100 seconds minutes - 15 minutes hours - 18 hours day - 1 day

40. Measurement API List> sortNaturalList = times.stream() .sorted(QuantityFunctions.sortNaturalDesc()) .collect(Collectors.toList()); day - 1 day hours - 18 hours minutes - 15 minutes seconds - 100 seconds

41. Measurement API times.add(Quantities.getQuantity(24, SI.HOUR)); Comparator> sortNatural = QuantityFunctions.sortNatural(); Comparator> sortSymbol = QuantityFunctions.sortSymbol(); List> sortNaturaAndSymbolList = times.stream() .sorted(sortNatural.thenComparing(sortSymbol)) .collect(Collectors.toList()); seconds - 100 seconds minutes - 15 minutes hours - 18 hours day - 1 day dayInHour 24 hours

42. Measurement API List> greaterThanOneDay = times .stream() .filter(QuantityFunctions.isGreaterThan(oneDay)).collect(Collect ors.toList()); List> greaterThanOneDay = times .stream().filter(QuantityFunctions.isBetween(oneHour, oneDay)).collect(Collectors.toList());

43. Measurement API Mixing Filters QuantityFunctions.isGreaterThan(oneDay).and(QuantityFunctio ns.fiterByUnit(SI.HOUR))); QuantityFunctions.isGreaterThan(oneDay).or(QuantityFunction s.fiterByExcludingUnit(SI.DAY)));

44. Measurement API QuantitySummaryStatistics summary = times.stream().collect(QuantityFunctions.summarizingMeasure( SI.HOUR)); //result in hours summary.getCount(); summary.getAverage(); summary.getMax(); summary.getMin(); summary.getSum();

45. Measurement API QuantitySummaryStatistics summaryDay = summary.to(SI.DAY); summary.getMin(SI.MINUTE); summary.getMax(SI.MINUTE); summary.getSum(SI.MINUTE); summary.getAverage(SI.MINUTE);

46. Measurement API Quantity t1 = timeFactory.create(1, DAY); Quantity m1 = timeFactory.create(12, KILOGRAM); Quantity l1 = timeFactory.create(12, KILOGRAM); t1.add(m1); //error Quantity s1 = l1.divide(t1).asType(Speed.class);

47. Measurement API Acceleration Length Angle Area Mass Power Energy Speed Force Temperature Time Information Volume And more! 52 quantities
