Java 7 introduced the diamond operator (``++<>++``) to reduce the verbosity of generics code. For instance, instead of having to declare a ``++List++``'s type in both its declaration and its constructor, you can now simplify the constructor declaration with ``++<>++``, and the compiler will infer the type.

*Note* that this rule is automatically disabled when the project's ``++sonar.java.source++`` is lower than ``++7++``.

== Noncompliant Code Example
|
|
|
|
----
|
|
List<String> strings = new ArrayList<String>(); // Noncompliant
|
|
Map<String,List<Integer>> map = new HashMap<String,List<Integer>>(); // Noncompliant
|

== Compliant Solution
|
|
|
|
----
|
|
List<String> strings = new ArrayList<>();
|
|
Map<String,List<Integer>> map = new HashMap<>();
