Redundant semicolon

Warning
Last modified: 03 December 2024

Reports redundant semicolons (;) that can be safely removed.

Kotlin does not require a semicolon at the end of each statement or expression. The quick-fix is suggested to remove redundant semicolons.

Example:

After the quick-fix is applied:

There are two cases though where a semicolon is required:

  1. Several statements placed on a single line need to be separated with semicolons:

    map.forEach { val (key, value) = it; println("$key -> $value") }
  2. enum classes that also declare properties or functions, require a semicolon after the list of enum constants:

    enum class Mode {
        SILENT, VERBOSE;
    
        fun isSilent(): Boolean = this == SILENT
    }
