Redundant semicolon

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:

val myMap = mapOf("one" to 1, "two" to 2); myMap.forEach { (key, value) -> print("$key -> $value")};

After the quick-fix is applied:

val myMap = mapOf("one" to 1, "two" to 2) myMap.forEach { (key, value) -> print("$key -> $value")}

There are two cases though where a semicolon is required:

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

    map.forEach { val (key, value) = it; println("$key -> $value") }
  • 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 }
