}1) Separating normal code from exception handling code to avoid abnormal
termination of program.
2) Categorizing in to different types of Exceptions so that rather than
handling all exceptions with Exception root class we can handle with specific
exceptions. It is recommended to handle exceptions with specific Exception
instead of handling with Exception root class.
3) Call stack mechanism : If a method throws an exception and it is not handled
immediately, then that exception is propagated or thrown to the caller of that
method. This propogation continues till it finds an appropriate exception
handler,if it finds handler it would be handled otherwise program terminates
abruptly.public class Main {
public static void main(String[ ] args) {
try {
int[] myNumbers = {1, 2, 3};
System.out.println(myNumbers[10]);
} catch (Exception e) {
System.out.println("Something went wrong.");
