How do I address unchecked cast warnings?

An unchecked cast warning in Java occurs when the compiler cannot verify that a cast is safe at compile time. This can happen when you are casting an object to a type that is not a supertype or subtype of the object's actual type.

To address an unchecked cast warning, you can either suppress the warning using the @SuppressWarnings("unchecked") annotation, or you can modify your code to ensure that the cast is safe.

To suppress the warning, you can add the @SuppressWarnings annotation to the method or block of code that contains the unchecked cast. For example:

@SuppressWarnings("unchecked")
public void foo() {
  List list = new ArrayList();
  List<String> stringList = (List<String>) list;
  // ...
}

To ensure that the cast is safe, you can modify your code to ensure that the object being cast is actually an instance of the target type. For example:

public void foo() {
  List list = new ArrayList();
  if (list instanceof List<String>) {
    List<String> stringList = (List<String>) list;
    // ...
  } else {
    // handle error
  }
}

I hope this helps! Let me know if you have any questions.
