Which of the following is a checked exception in Java? Question 3Answera.NullPointerExceptionb.ArrayIndexOutOfBoundsExceptionc.IOExceptiond.ArithmeticException

The checked exception in Java from the given options is c.IOException.

Here's why:

In Java, exceptions are divided into two main categories: checked and unchecked exceptions.

Checked exceptions are exceptions that are checked at compile-time. If some code within a method throws a checked exception, then the method must either handle the exception or it must specify the exception using throws keyword. IOException is a checked exception.

On the other hand, NullPointerException, ArrayIndexOutOfBoundsException, and ArithmeticException are all unchecked exceptions. Unchecked exceptions are not checked at compile-time, but they are checked at runtime. These are also called as Runtime Exceptions.
