.removePrefix()

The .removePrefix() method in Kotlin is used to remove a specified prefix from a string if it is present. It returns a new string with the specified prefix removed if it exists. If the original string does not start with the specified prefix, the method returns the original string unchanged.

Syntax

String.removePrefix(prefix)

• String: The original string from which the prefix will be removed.
• prefix: The prefix which will be removed from the original string.

Example

This example shows how to use the .removePrefix() method to remove a prefix from a Kotlin string:

fun main() {
  val originalString = "HelloWorld.jpg"
  val prefix = "Hello"
  val modifiedString = originalString.removePrefix(prefix)

  println("Modified String: $modifiedString")
}

The result will be printed as:

Modified String: World.jpg
