Method/constructor references are more compact and readable than using lambdas, and are therefore preferred.

Note that this rule is automatically disabled when the project's sonar.java.source is lower than 8.

Noncompliant Code Example

  List list = new ArrayList();
  list.add(0);
  list.add(1);
  list.add(2);

    list.forEach(n -> { System.out.println(n); });

Compliant Solution

  List list = new ArrayList();
  list.add(0);
  list.add(1);
  list.add(2);

  list.forEach(System.out::println);
