In Kotlin, there are two types of string literals: an escaped string with some escaped character in it; a raw string Index 0 represents the first element, index 1 represents the second element and so on. lastIndex: Represents the index of last character in string. At some point, you may need to get a substring using a defined delimiter parameter. Kotlin strings are also immutable in nature means we can not change elements and length of the String. 3. concatToString() function Alternatively, you can use concatToString() function which concatenates characters of the CharArray into a String.
