== Noncompliant Code Example

----
public class S1944 {

  public static void main(String[] args) {
    List<String> list = (List<String>) getAttributes(); // Noncompliant; List<Integer> return by getAttributes() is not be casted to List<String> 
    String s = list.get(0); // java.lang.ClassCastException will be raised here
  }

  private static List<?> getAttributes() {
    List<Integer> result = new ArrayList<>();
    result.add(0);
    return result;
  }

}
----

== Compliant Solution

----
public class S1944 {

  public static void main(String[] args) {
    List<Integer> list = (List<Integer>) getAttributes(); // Compliant
    String s = String.valueOf(list.get(0));
  }

  private static List<?> getAttributes() {
    List<Integer> result = new ArrayList<>();
    result.add(0);
    return result;
  }
