This compliant solution enforces type safety by changing the addToList() method signature to enforce proper type checking.:
| Code Block | ||
|---|---|---|
| ||
class ListUtility {
private static void addToList(List<String> list, String str) {
list.add(str); // No warning generated
}
public static void main(String[] args) {
List<String> list = new ArrayList<String> ();
addToList(list, "42");
System.out.println(list.get(0));
}
}
