Cardinalities

• CARDINALITY_ONE

  Matches i = 1 and v = 0

  Example Integers: 1

• CARDINALITY_OTHER

  Matches all other values

  Example Integers: 0, 2, 16, 100, 1000, 10000, 100000, 1000000, …

  Example Decimals: 0.0, 1.5, 10.0, 100.0, 1000.0, 10000.0, 100000.0, 1000000.0, …

Cardinality example

This localized strings file selects the localized form of “day” for a delivery estimate. Raw numbers choose the CLDR category; values formatted with the JDK NumberFormat are interpolated for display.

Sample localized strings file

{
  "Delivery.LeadTime": {
    "commentary": "Estimated delivery time, expressed in days.",
    "translation": "{{leadTime}}",
    "placeholders": {
      "leadTime": {
        "value": "dayCount",
        "translations": {
          "CARDINALITY_ONE": "{{formattedDayCount}} dag",
          "CARDINALITY_OTHER": "{{formattedDayCount}} dagen"
        }
      }
    }
  }
}

Usage and expected results

The Java code passes each raw number for cardinality selection and formats its display value separately with NumberFormat.

Locale locale = Locale.forLanguageTag("nl");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

// Raw numbers select language forms; NumberFormat produces the display values

// CARDINALITY_ONE
Number oneDayCount = 1;
String oneFormattedDayCount = numberFormat.format(oneDayCount);

assertEquals(Cardinality.ONE, Cardinality.forNumber(oneDayCount, locale));

// Expected: 1 dag
assertEquals(oneFormattedDayCount + " dag", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", oneDayCount, "formattedDayCount", oneFormattedDayCount)
));

// CARDINALITY_OTHER
Number otherDayCount = 0;
String otherFormattedDayCount = numberFormat.format(otherDayCount);

assertEquals(Cardinality.OTHER, Cardinality.forNumber(otherDayCount, locale));

// Expected: 0 dagen
assertEquals(otherFormattedDayCount + " dagen", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", otherDayCount, "formattedDayCount", otherFormattedDayCount)
));

Cardinality Ranges

These are CLDR's explicit range mappings. For any start/end pair not listed, Cardinality.forRange(...) falls back to the ending cardinality.

• CARDINALITY_ONE - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

• CARDINALITY_OTHER - CARDINALITY_ONE

  Matches CARDINALITY_ONE

• CARDINALITY_OTHER - CARDINALITY_OTHER

  Matches CARDINALITY_OTHER

Cardinality range example

The start and end cardinalities select the locale's CLDR range result. The selected form wraps a separately formatted display range.

Sample localized strings file

{
  "Delivery.Window": {
    "commentary": "Estimated delivery window, expressed as a range of days.",
    "translation": "{{window}}",
    "placeholders": {
      "window": {
        "range": {
          "start": "minDays",
          "end": "maxDays"
        },
        "translations": {
          "CARDINALITY_ONE": "{{formattedDayRange}} dag",
          "CARDINALITY_OTHER": "{{formattedDayRange}} dagen"
        }
      }
    }
  }
}

Usage and expected results

The Java code passes raw range endpoints for selection. Because NumberFormat formats one number at a time, it formats both endpoints separately and joins them for display; choose range punctuation appropriate to your application.

Locale locale = Locale.forLanguageTag("nl");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

// Raw numbers select language forms; NumberFormat produces the display values

// CARDINALITY_OTHER range
Number minDays = 1;
String formattedMinDays = numberFormat.format(minDays);
Number maxDays = 2;
String formattedMaxDays = numberFormat.format(maxDays);
String formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

assertEquals(Cardinality.OTHER, Cardinality.forRange(
  Cardinality.forNumber(minDays, locale),
  Cardinality.forNumber(maxDays, locale),
  locale
));

// Expected: 1-2 dagen
assertEquals(formattedDayRange + " dagen", strings.get(
  "Delivery.Window",
  Map.of("minDays", minDays, "maxDays", maxDays, "formattedDayRange", formattedDayRange)
));

Ordinalities

All ordinal numbers use ORDINALITY_OTHER; no value selects a different form.

Example: Neem de 2e afslag rechts..

Language-Specific Examples

These examples show how Lokalized models grammatical choices and translation behavior that commonly affect Dutch application copy. Each example identifies the Lokalized language forms and other library features it uses.

{
  "Create a new item.": {
    "translation": "Maak {{item}}.",
    "placeholders": {
      "item": {
        "value": "gender",
        "translations": {
          "GENDER_COMMON": "een nieuwe map",
          "GENDER_NEUTER": "een nieuw document"
        }
      }
    }
  }
}

Locale locale = Locale.forLanguageTag("nl");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

assertEquals("Maak een nieuwe map.", strings.get(
  "Create a new item.", Map.of("gender", Gender.COMMON)
));

assertEquals("Maak een nieuw document.", strings.get(
  "Create a new item.", Map.of("gender", Gender.NEUTER)
));

Addendum: Language Form Rules

The language form expressions above are specified by Unicode Technical Standard #35 and use the following notation:

• n absolute value of the source number (integer and decimals)
• i integer digits of n
• v number of visible fraction digits in n, with trailing zeros
• w number of visible fraction digits in n, without trailing zeros
• f visible fractional digits in n, with trailing zeros
• t visible fractional digits in n, without trailing zeros
• c/e compact decimal exponent operands used by some CLDR compact-number rules
