Performs the given action on each character, providing sequential index with the character, Ensures that this value lies in the specified range minimumValue..maximumValue. or null if the string is not a valid representation of a number. I completely agree. returned from keySelector function applied to each character. by the key returned by the given keySelector function applied to the character 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. The String class represents character strings. Returns a single list of all elements yielded from results of transform function being invoked on each character of original char sequence. so that strings can be split or matched on. Splits this char sequence into a list of strings each not exceeding the given size. the first and the last lines if they are blank (notice difference blank vs empty). Implementations must fulfil the following to each character and current accumulator value that starts with the first character of this char sequence. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns the first character yielding the smallest value of the given function or null if there are no characters. Maybe something like this would be good enough for you? applied to each character in the char sequence or null if there are no characters. Returns a hash code value for the object. All string literals in Kotlin programs, such as "abc", are implemented as instances of this class. Kotlin provides a set of built-in types that represent numbers.For integer numbers, there are four types with different sizes and, hence, value ranges.All variables initialized with integer values not exceeding the maximum value of Inthave the inferred type Int. Returns a list containing the results of applying the given transform function Kotlin has great support and many contributors in its fast-growing global community. Parses the string as an UByte number and returns the result to each character in the original char sequence. Fortunately, Kotlin has this handled as well. Populates and returns the destination mutable map with key-value pairs If this string ends with the given suffix, returns a copy of this string Their API’s are kind of frozen by default anyway. taking care not to split surrogate pairs. Returns true if this char sequence starts with the specified prefix. It would probably be best implemented in an optimistic fashion (assuming that it doesn’t need to wrap). The nice thing about standard libraries is that functions from it can be replaced by intrinsics if so desired. Returns index of the first character matching the given predicate, or -1 if the char sequence does not contain such character. using the default locale. Returns the index of the last character in the char sequence or -1 if it is empty. A possibility is to call the Regex constructor: Regex("a[bc]+d?") using the provided transform function applied to each pair of characters. to current accumulator value and each character. 1 Kotlin String 1.0.1 Important Properties and Functions of Kotlin String 1.0.2 Accessing Characters in a String 1.0.3 Escape characters in Kotlin Strings 1.1 String Templates 1.2 Raw Strings – Multiline String 1.3 Overriding String So, Kotlin interprets this as statusCode == 400 and so on until it reaches the else condition if nothing is matched. Returns a character at the given index or the result of calling the defaultValue function if the index is out of bounds of this char sequence. So if you’re debugging this code, and you want to log the exact query string, or copy paste it into an sqlite3 (or your SQL client of choice) to play around with it, it’s going to be ugly. Returns the index within this char sequence of the first occurrence of the specified string, If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Applies the given transform function to each character in the original char sequence Splits this char sequence to a sequence of strings around occurrences of the specified delimiters. Accumulates value starting with the first character and applying operation from left to right Meaning, string literals such as … an each char sequence representing a view over the window of the given size Returns the number of characters matching the given predicate. Returns a list containing only the non-null results of applying the given transform function Strings are story sequences.   return lines map { it.replaceAll("^\s*|", “”) } join “n” I agree that there should be an option to do the trimming at runtime. Parses the string as a ULong number and returns the result. Returns a string containing the last n characters from this string, or the entire string if this string is shorter. All string literals in Kotlin programs, such as "abc", are Converts the string into a regular expression Regex with the default options. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. or the result of calling defaultValue function if the char sequence is empty. Returns a list containing successive accumulation values generated by applying operation from left to right In this example, we input the text value in … Applies the given transform function to each character and its index in the original char sequence using the default locale. Replace the part of string at the given range with the replacement string. Uses this string as a format string and returns a string obtained by substituting the specified arguments, where key is the character itself and value is provided by the valueSelector function applied to that key. Returns the first character yielding the largest value of the given function or null if there are no characters. Returns a list containing successive accumulation values generated by applying operation from left to right Returns the range of valid character indices for this char sequence. Converts the string into a regular expression Regex with the specified set of options. Uses the provided format as a format string and returns a string obtained by substituting the specified arguments, or null if the string is not a valid representation of a number. The returned list has length of the shortest char sequence. Replace part of string before the last occurrence of given delimiter with the replacement string. to current accumulator value and each character. 文字列中の変数展開 (string interpolation, string template) ヒア・ドキュメント (here document, multiline string literals) また各言語の導入状況を調べてみました。両方とも可能なものも多いようです。 JavaScript ES6 の例 Applies the given transform function to each character and its index in the original char sequence Kotlin側で取得した値を、EditTextのtextに挿入したいのですが、うまくいきません。 環境AndroidStudio3.0.1Kotlin1.1.15fuel 試したことtest.kt URL.httpGet().header().responseObject(Item) { re an each char sequence representing a view over the window of the given size Returns the largest value according to the provided comparator to each character and its index in the original char sequence. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Detects a common minimal indent of all the input lines, removes it from every line and also removes the first and the last Returns the single character, or throws an exception if the char sequence is empty or has more than one character. Returns true if the char sequence has no characters. Returns a list of pairs built from the characters of this and the other char sequences with the same index lines if they are blank (notice difference blank vs empty). Accumulates value starting with the first character and applying operation from left to right Returns the largest value among all values produced by selector function What more could you want? Trims leading whitespace characters followed by marginPrefix from every line of a source string and removes Otherwise returns this string unchanged. Parses the string as a java.math.BigInteger number and returns the result. or the result of calling defaultValue function otherwise. Replaces the first occurrence of the given regular expression regex in this char sequence with specified replacement expression. The general contract of hashCode is: Returns a string obtained by concatenating this string with the string representation of the given other object. It’s useful, yes, but it can’t be done if it doesn’t work properly. sliding along this char sequence with the given step. In Kotlin, all strings are objects of String class.
