== Why is this an issue?

include::../description.adoc[]

=== Exceptions

To prevent generating some false-positives, literals having 5 or less characters are excluded as well as literals containing only letters, digits and '_'.

== How to fix it

include::../howtofix.adoc[]

=== Code examples

==== Noncompliant code example

With the default threshold of 3:

[source,kotlin,diff-id=1,diff-type=noncompliant]
----
class A {
    fun run() {
        prepare("string literal")    // Noncompliant - "string literal" is duplicated 3 times
        execute("string literal")
        release("string literal")
    }

    fun method() {
        println("'")                 // Compliant - literal "'" has less than 5 characters and is excluded
        println("'")
        println("'")
    }
}
----

==== Compliant solution

[source,kotlin,diff-id=1,diff-type=compliant]
----
class A {
    companion object {
        const val CONSTANT = "string literal"
    }

    fun run() {
        prepare(CONSTANT)    // Compliant
        execute(CONSTANT)
        release(CONSTANT)
    }
}
