== Why is this an issue?
|
|
|
|
include::../description.adoc[]
|
|
|
|
Code like
|
|
|
|
[source,kotlin]
|
|
----
|
|
if (condition1) {
|
|
if (condition2) { // Noncompliant
|
|
/* ... */
|
|
}
|
|
}
|
|
----
|
|
|
|
Will be more readable as
|
|
|
|
[source,kotlin]
|
|
----
|
|
if (condition1 && condition2) { // Compliant
|
|
/* ... */
|
|
}
|
|
----
|
|
|
|
|
|
== How to fix it
|
|
|
|
If merging the conditions seems to result in a more complex code, extracting the condition or part of it in a named function or variable is a better approach to fix readability.

=== Code examples

==== Noncompliant code example

|
include::../noncompliant.adoc[]
|
|
|
|
==== Compliant solution
|
|
|
|
[source,kotlin]
|
|
----
|
|
if (file != null && isFileOrDirectory(file)) { // Compliant
|
|
/* ... */
|
|
}
|
|
fun isFileOrDirectory(file: File): Boolean {
|
|
return file.isFile() || file.isDirectory();
|

}
