Divisão de Strings no Kotlin

Kotlin splits strings using a given set of delimiters or regular expressions-It is very useful to split a string into multiple parts using delimiters when the string contains many (parameter) values separated by delimiters or when the string is similar to a regular expression. In this tutorial, we will learn how to split strings in Kotlin using the given delimiter or regular expression.

* A delimiter is a character or another string that connects multiple strings into a single string.

Kotlin splits strings using delimiters

In the following example, we will use the delimiter sep to split the string "stringKotlin TutorialsepTutorialsepw"3codebox.com”。

fun main(args: Array<String>) {
　
　　　　var str = "Kotlin TutorialsepTutorial Kotlinsepw"3codebox.com"
　　　　var delimiter = "sep"
　
　　　　val parts = str.split(delimiter)
　
　　　　print(parts)
}

You can also provide multiple delimiters as parameters for the String class's split() method. The syntax is as follows:

String.　split(delimiter1,　delimiter2,　..,　delimiterN)

In the following example, we will use two delimiters sep, asep to split the string Kotlin TutorialsepTutorialasepoldtoolbag.comsepExamples example.

fun main(args: Array<String>) {
　
　　　　var　str　=　"Kotlin　TutorialsepTutorialasepoldtoolbag.comsepExamples"
　　　　var　delimiter1　=　"sep"
　　　　var　delimiter2　=　"asep"
　
　　　　val　parts　=　str.split(delimiter1,　delimiter2)
　
　　　　print(parts)
}

Kotlin splits strings ignoring case

The split () method accepts a boolean value as the second parameter after the delimiter, which is used to determine whether to ignore the case of the delimiter and the string during the split.

String.　split(vararg　delimiters,　ignoreCase:Boolean　=　false)

The default parameter for ignoreCase is false. To ignore case, you must provide true as a named parameter to ignoreCase. In the following example, we will use two delimiters SEP, ASEP to split the string stringKotlin TutorialsEPTutorialaSEpKotlinSEpExamples.

fun main(args: Array<String>) {
　
　　　　var　str　=　"Kotlin　TutorialsEPTutorialaSEpKotlinSEpExamples"
　　　　var　delimiter1　=　"SEP"
　　　　var　delimiter2　=　"ASEP"
　
　　　　val　parts　=　str.split(delimiter1,　delimiter2,　ignoreCase　=　true)
　
　　　　print(parts)
}

Kotlin uses regular expressions to split strings

In the following example, we will use the regular expression sep|asep to split the string Kotlin TutorialsepTutorialasepKotlinsepExamples.

fun main(args: Array<String>) {
　
　　　　var str = "Kotlin TutorialsepTutorialasepKotlinsepExamples"
　
　　　　val parts = str.split(Regex("sep|asep"))
　
　　　　print(parts)
}
