### Question:
UtilsValidator { public static boolean isEqualTo(String a, String b) { return StringUtils.equals(a, b); }  static T get(JsonNode jsonValue, String key); static boolean isEqualTo(String a, String b); static boolean isDifferentFrom(String a, String b); static boolean isEqualTo(Number a, Number b); static boolean isDifferentFrom(Number a, Number b); static boolean isGreaterThan(Number a, Number b); static boolean isLowerThan(Number a, Number b); static boolean isGreaterThanOrEqual(Number a, Number b); static boolean isLowerThanOrEqual(Number a, Number b); static boolean isGreaterThan(Date date, int count, TimeUnit unit); static boolean isLowerThan(Date date, int count, TimeUnit unit); static boolean isGreaterThanOrEqual(Date date, int count, TimeUnit unit); static boolean isLowerThanOrEqual(Date date, int count, TimeUnit unit); static Boolean checkPresent(JsonNode jsonValue, String... keys);  }### Answer:
@Test public void toCamelCase() { assertThat(RuleToJava.toCamelCase("my rule name")).isEqualTo("MyRuleName"); assertThat(RuleToJava.toCamelCase("my_rule_name")).isEqualTo("MyRuleName"); assertThat(RuleToJava.toCamelCase("épique test")).isEqualTo("EpiqueTest"); }
