### Question:
PrimitiveMapperFactory implements ValueMapperFactory { public static boolean parseBoolean(String string) { if ("false".equals(string)) { return false; } if ("true".equals(string)) { return true; } throw BooleanFormatException.forInputString(string); } PrimitiveMapperFactory(); @Override Optional<ValueMapperInstance<?>> maybeForType(BindingType bindingType); static boolean parseBoolean(String string); static char parseChar(String string);  }### Answer:
@Test void bools() { assertThat(PrimitiveMapperFactory.parseBoolean("true")).isTrue(); assertThat(PrimitiveMapperFactory.parseBoolean("false")).isFalse(); }
