Does an exception that occurs during runtime belong to checked exception types in the programming language?

In Java, exceptions are divided into checked and unchecked. Checked exceptions are those that inherit from the Exception class but not from RuntimeException. The compiler requires such exceptions to be either handled within a try-catch block or declared in the method signature using throws.

Runtime exceptions, which occur during execution, are generally considered unchecked exceptions (RuntimeException and its subclasses). They do not require mandatory handling or declaration, as they usually indicate programming errors (e.g., NullPointerException, ArrayIndexOutOfBoundsException).

Thus, not all runtime exceptions are checked. Checked exceptions are those that the compiler forces you to handle explicitly or declare.
