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.


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


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
