Cardinality example
This localized strings example uses complete, page-local CLDR minimal-pair patterns to demonstrate every Cardinality category defined for the locale. Minimal-pair text contrasts grammatical forms; it is language-reference data, not reusable application copy.
Source: Unicode CLDR 48.2 csw locale data.
Sample localized strings file
{ "Cardinality.MinimalPair": { "commentary": "Demonstrates every CLDR cardinal category defined for this locale.", "translation": "{{cardinalityExample}}", "placeholders": { "cardinalityExample": { "value": "cardinalityValue", "translations": { "CARDINALITY_ONE": "{{formattedCardinalityValue}} ᑮᓯᑳᐤ", "CARDINALITY_OTHER": "{{formattedCardinalityValue}} ᑮᓯᑳᐘ" } } } } }
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("csw"); 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 oneCardinalityValue = 0; String oneFormattedCardinalityValue = numberFormat.format(oneCardinalityValue); assertEquals(Cardinality.ONE, Cardinality.forNumber(oneCardinalityValue, locale)); // Expected: 0 ᑮᓯᑳᐤ assertEquals(oneFormattedCardinalityValue + " ᑮᓯᑳᐤ", strings.get( "Cardinality.MinimalPair", Map.of( "cardinalityValue", oneCardinalityValue, "formattedCardinalityValue", oneFormattedCardinalityValue ) )); // CARDINALITY_OTHER Number otherCardinalityValue = 2; String otherFormattedCardinalityValue = numberFormat.format(otherCardinalityValue); assertEquals(Cardinality.OTHER, Cardinality.forNumber(otherCardinalityValue, locale)); // Expected: 2 ᑮᓯᑳᐘ assertEquals(otherFormattedCardinalityValue + " ᑮᓯᑳᐘ", strings.get( "Cardinality.MinimalPair", Map.of( "cardinalityValue", otherCardinalityValue, "formattedCardinalityValue", otherFormattedCardinalityValue ) ));
Cardinality Ranges
No explicit CLDR cardinality-range mapping is defined for this language. Cardinality.forRange(...) therefore falls back to the ending cardinality for every range.
Ordinalities
All ordinal numbers use ORDINALITY_OTHER; no value selects a different form.
Addendum: Language Form Rules
The language form expressions above are specified by Unicode Technical Standard #35 and use the following notation:
