This document discusses exception handling in Java. It introduces exceptions as problems that occur during program execution and disrupt normal flow. It outlines the hierarchy of exceptions and describes the main types - checked exceptions, unchecked exceptions, and errors. It also lists common exception handling keywords like try, catch, finally, throw, and throws. Finally, it provides an example Java code snippet demonstrating how to catch an ArrayIndexOutOfBoundsException.

3. INTRODUCTION
 The Exception Handling in Java is one of the powerful mechanism to
handle the runtime errors so that the normal flow of the application
can be maintained.
What are Exception?
An exception is a problem that arises during the execution of a
program. When an Exception occurs the normal flow of the program
is disrupted and the program terminates abnormally, which is not
recommended, therefore, these exceptions are to be handled.

7. Example
Example of exception handling in Java:
public class Example {
public static void main(String[] args) {
try {
int[] arr = new int[3];
arr[4] = 5;
} catch (ArrayIndexOutOfBoundsException e) {
System.out.println("An array index is out of bounds.");
}
