Kotlin String Operations

Kotlin String Operations

In this tutorial, we shall learn different string operations that are available in Kotlin programming language.

String Tutorials

Basics

• Kotlin – Initialize string
• Kotlin – Create empty string
• Kotlin – Define a string constant

• Kotlin – Check is string matches regular expression

Finds

Character specific Operations

• Kotlin – Get character at specific index in string

String Collections

• Kotlin – List of strings
• Kotlin String List – Filter based on Length
