Can you list exceptions in Java that do not require mandatory handling or checking?

In Java, exceptions are divided into checked and unchecked. Exceptions that do not require mandatory handling (via try-catch) or declaration in the method signature (throws) are considered unchecked exceptions.

They include:

• Subclasses of RuntimeException:

  • NullPointerException
  • ArrayIndexOutOfBoundsException
  • IllegalArgumentException
  • ArithmeticException
  • ClassCastException
  • and others

• Subclasses of Error (for example, OutOfMemoryError, StackOverflowError), which are usually not handled in the application.

Example:

public void example() {
    int a = 5 / 0; // will throw ArithmeticException, but does not require try-catch
}
