## Metadata{% #metadata %}

**ID:** `kotlin-code-style/no-consecutive-comments`

**Language:** Kotlin

**Severity:** Notice

**Category:** Code Style

## Description{% #description %}

Consecutive block comments are not allowed. However, block comments followed by line comments and vice versa are allowed, as long as there is at least one blank line between them.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```kotlin
/*
 * Block comments can not be consecutive ...
 */

/*
 * ... even when separated by a new line.
 */

// Two comments
/* With no line in between */
// Foo
```

## Compliant Code Examples{% #compliant-code-examples %}

```kotlin
// An EOL comment
// may be followed by another EOL comment
val foo = "foo"

// Different comment types (including KDoc) may be consecutive ..

/*
 * ... but do need to be separated by a blank line ...
 */

// ... as demonstrated here
```
