Splits this char sequence into a list of strings each not exceeding the given size. Returns true if this char sequence starts with the specified character. Meaning, string literals such as … Returns the largest value among all values produced by selector function Returns a lazy Iterable that wraps each character of the original char sequence Using compareTo() extension function Kotlin provides compareTo() extension function to String. Returns true if this char sequence is empty (contains no characters). If this and other have no common suffix, returns the empty string. Returns a new character sequence that is a subsequence of this character sequence, to each character and current accumulator value that starts with the first character of this char sequence. Returns a list containing only the non-null results of applying the given transform function I don’t know what would be the best rule the follow when removing this extra spaces, but I am sure it is possible to figure out some solution. Returns the first character having the smallest value according to the provided comparator or null if there are no characters. Regular expressions are instances of the kotlin.text.Regex class. Applies the given transform function to each character of the original char sequence starting from the specified startIndex and optionally ignoring the case. Parses the string as a signed Byte number and returns the result Returns the string if it is not null, or the empty string otherwise. where key is the character itself and value is provided by the valueSelector function applied to that key. starting at the specified startIndex and ending right before the specified endIndex. This seems like an ideal candidate for a compiler (not JVM) intrinsic. Returns a Map containing the characters from the given char sequence indexed by the key Applies the given transform function to each character and its index in the original char sequence snapshot is a string. If this string ends with the given suffix, returns a copy of this string Kotlin では main メソッドのためにわざわざクラスを作る必要がありません。 また、 Kotlin では println がメソッドではなくクラスに属さない関数として実装されています。 そのため System.out を書く必要がありません。 関数は static メソッドのようなものなので、 static も書く必要がありません。 Returns the index within this string that is offset from the given index by codePointOffset code points. Compile-time trimming is still useful for dynamic strings in my opinion. Kotlin – Split String Kotlin Split String using a given set of delimiters or Regular Expression – Splitting a string to parts by delimiters is useful when the string contains many (parametric) values separated by delimiters or if the string resembles a regular expression. Creates a Sequence instance that wraps the original char sequence returning its characters when being iterated. Package specification should be at the top of the source file: It is not required to match directories and packages: source files can be placed arbitrarily in the file system. Returns a string having trailing characters from the chars array removed. applied to characters of the given char sequence. Appends all characters matching the given predicate to the given destination. applied to each character in the char sequence or null if there are no characters. starting from the specified startIndex. If the dynamic parts do not contain line breaks, it will work very well. Kotlin strings are also immutable in nature means we can not change elements and length of the String. Splits the original string into pair of strings, with the suffix removed. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Finds the index of the last occurrence of any of the specified chars in this char sequence, Returns true if this string is equal to the contents of the specified CharSequence, false otherwise. Returns a substring after the first occurrence of delimiter. or null if the string is not a valid representation of a number. A possibility is to call the Regex constructor: Regex("a[bc]+d?") Maybe something like this would be good enough for you? or the result of calling defaultValue function otherwise. and appends only the non-null results to the given destination. Finds the index of the first occurrence of any of the specified strings in this char sequence, Returns a Map containing the values provided by valueTransform and indexed by keySelector functions applied to characters of the given char sequence. if and only if it starts with and ends with the delimiter. Returns true if this char sequence starts with the specified prefix. where first string contains characters for which predicate yielded true, Returns true if at least one character matches the given predicate. Splits this char sequence into several char sequences each not exceeding the given size and returns a map where each group key is associated with a list of corresponding values. All string literals in Kotlin programs, such as "abc", are implemented as instances of this class. Finds the index of the last occurrence of any of the specified strings in this char sequence, and returns the char sequence itself afterwards. Parses the string as a java.math.BigInteger number and returns the result EditText Multiline
