Exception Handling in Java

Hello Readers, in the previous blog we learn about Interface Concept, in this blog we are going to learn about the Exception Handling.

Exception handling is a mechanism in Java that deals with runtime errors or exceptional situations that may occur during the execution of a program.

These exceptions can be caused by various reasons, such as invalid user input, file not found, network issues, and so on.

Handling exceptions allows you to gracefully manage such situations and prevent your program from crashing.

In Java, exception handling is done using the try, catch, finally , and throw keywords.

A basic overview of how exception handling works in Java:

1. try Block: The code that might raise an exception is placed within a try block.

2. catch Block: If an exception occurs within the try block, it is caught by a corresponding catch block. You can have multiple catch blocks to handle different types of exceptions.

3. finally Block : The finally block is used to specify code that will be executed regardless of whether an exception is thrown or not. It is optional.

4.throw Statement: We can manually throw an exception using the throw statement. This is useful when you want to explicitly indicate that an exceptional condition has occurred.

Let try simple Example :

In this example, if the user enters “0” or a non-numeric value, it will catch the appropriate exception and display an error message. The finally block ensures that the Scanner is closed, even if an exception occurs.

So this is all about the Exception Handling in Java. We will meet in the next blog.
