Why is this an issue?
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;
