OrdinalIgnoreCase)); would return true?While conceivable correct, I'd prefer a Contains on List<string> that only returns true if the length of both strings are equal, regardless of case rather that one that returns true if the List<string> contains a string that contains the @JulienKronegg I don't think I agree. Collection c = CollectionUtils. IndexOf(toCheck, comp) >= 0; } } That should be really simple question I believe. Parameters (expressions not allowed): patset_name- Pattern Set Name Parameters. regionMatches(). filter(list1, new Predicate<String>() { public boolean apply(String input) ignoreCase : if true, ignores case when comparing characters. It (being slow) doesn't matter if you just want to check in one case. contains# Series. It checks for null as well as size of collections. Use StringComparison. Meaning; you do something like: @Test public void testWithEmptyMap() { UnderTest underTest = new Try to use subtract method of org. In that case you can't use the lower-case() function, but you can use translate() to replace a collection of characters with their lower-case representation. This is an interesting question from an OO perspective. This method is The contains(Object element) of java. toLowerCase()); Collection<String> toRemove = Collections2. isEmpty(listObject); CollectionUtils. This Spring Data query: ExampleMatcher matcher = ExampleMatcher. 36% off. message.

Returns ¶ The returned value is the specified element of the ARRAY, or the value that corresponds to the specified key of a key-value pair in the OBJECT. isEmpty is NullSafe and as you say that you know that collection is not empty , so Both are equally Good (Almost) About Pegasystems. ignoreCase If facet. These utility methods perform common, often reused functions and they don't require no have object level state, that is they tend to be global functions. The CollectionUtil isEmpty() method used to chek a collection is empty or not. CollectionUtils class. The simplest solution is to use regular expressions and the word boundary delimiter \b:. There are a couple of approaches here. matching(). contains. Also not using java 8 so unable to do stream. This outputs the following: 'Welcome to Earth!' contains 'earth' Code language: plaintext (plaintext) Use string. result contains 1 of each element that has at least one copy in both a and b; result contains each element (including duplicates) that was in a, except those that are not in b; or even, result contains somewhere between 1 and the number of copies found in a of each element in a, except those not in b. If idx exceeds the number of entries in the map, an empty Iterator is returned. matches If you want to only return facet buckets for the terms that match a regular expression. Use dynamic expressions to modify and verify data in strings. The Spring Batch StoredProcedureItemReader is similar to JdbcCursorItemReader where for common cases we replace the SQL property with procedure name. contains(searchText. Some basic Hamcrest matchers are built into JUnit and JUnit has the assertThat built in so this is not something totally new. findValueOfType(java. if(str == null || searchStr == null) The org. Follow oops, the same thing was happening for me (but I realised the object I was trying to use contains on wasn't a String!) once I called toString first it was fine i. Tests findValueOfType(Collection<?> collection, Class<T> type) Find a single value of the given type in the given Collection. public isEqualCollection(Collection<? extends E> a, Collection<? extends E> b, Equator<? super E> equator) Let’s see an isEqualCollection() method example where we will pass Equator as Either store lowercase/uppercase strings only and check it with List#contains(s. CollectionUtils isEqualCollection() example using Equator. Of course, checking incoming arguments as early as possible, to avoid detaching the source of the problem from the place where the exception occurs, is a good thing. There are no guarantees on the type or serializability of the list returned, so if more control over the returned list is required, consider creating a new Collector implementation like the following: public static <T> Collector<T, ?, List<T>> toUnmodifiableList(Supplier<List<T The section handling multi-valued attributes uses CollectionUtils to return a new list that will contain a substraction of the old values from the new values, but the substraction doesnt handle case insensitivity thus resulting in a list of items that require to be added which already exist in the Directory Server with a different case and Operations on String that are null safe.

This function doesn't support wildcards or If you use Equals to check two strings for equality, there's an overload that takes in a StringComparison enum value. I was thinking in the context of the LINQ extension method for String. It contains a collection of utility classes, one of which is the StringUtils class.
