Map.forEach() can be used

Suggests replacing for(Entry<?,?> entry : map.entrySet()) {...} or map.entrySet().forEach(entry -> ...) with map.forEach((key, value) -> ...).

Example

void print(Map<String, Integer> map) {
  map.entrySet().forEach(entry -> {
    String str = entry.getKey();
    System.out.println(str + ":" + entry.getValue());
  });
}

After the quick-fix is applied:

void print(Map<String, Integer> map) {
  map.forEach((str, value) -> System.out.println(str + ":" + value));
}

When the Do not report loops option is enabled, only entrySet().forEach() cases will be reported. However, the quick-fix action will be available for for-loops as well.

This inspection only reports if the language level of the project or module is 8 or higher.
