      Description

      Generic types shouldn't be used raw (without type parameters) in variable declarations or return values. Doing so bypasses generic type checking, and defers the catch of unsafe code to runtime.

      Noncompliant Code Example

      List myList; // Noncompliant 
Set mySet; // Noncompliant

      Compliant Solution

      List<String> myList;
Set<? extends Number> mySet;
