Which are checked exceptions?

Checked exceptions are the subclass of the Exception class. These types of exceptions occur during the compile time of the program. ClassNotFoundException, IOException, SQLException etc are the examples of the checked exceptions.

Which of the following is not checked exception?

Explanation: ArithmeticException is an unchecked exception, i.e., not checked by the compiler.

What is checked exception in Java?

Checked exceptions are also known as compile-time exceptions as these exceptions are checked by the compiler during the compilation process to confirm whether the exception is handled by the programmer or not. If not, then the system displays a compilation error.

Why checked exceptions are not propagated in Java?

1 Answer. Because you haven’t declared them in the method declaration. Checked exceptions must either be handled in the method where they can occur, or they must be declared to be “thrown” by that method.

How does the Java compiler check an exception?

The Java compiler checks the checked exceptions during compilation to verify that a method that is throwing an exception contains the code to handle the exception with the try-catch block or not. And, if there is no code to handle them, then the compiler checks whether the method is declared using the throws keyword.
