In Java, Exception is an unwanted or unexpected event, which occurs during the execution of a program, i.e. at run time, that disrupts the normal flow of the program’s instructions. Exceptions can be caught and handled by the program. When an exception occurs within a method, it creates an object. This object is called the exception object.
Definition: An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. When an error occurs within a method, the method creates an object and hands it off to the runtime system.
Exception handling is a programming concept used to manage errors that occur during the execution of a program. When an error occurs, the normal flow of the program is disrupted. The program creates an “exception” object that contains information about the error. The process of responding to this exception is called “exception handling”.

In general, an exception breaks the normal flow of execution and executes a pre-registered exception handler; the details of how this is done depend on whether it is a hardware or software exception and how the software exception is implemented.
1. Overview. In this tutorial, we’ll go through the basics of exception handling in Java as well as some of its gotchas. 2. First Principles. 2.1. What Is It? To better understand exceptions and exception handling, let’s make a real-life comparison. Imagine that we order a product online, but while en-route, there’s a failure in delivery.
An exception is an unexpected event that occurs during program execution. It affects the flow of the program instructions which can cause the program to terminate abnormally. An exception can occur for many reasons.
We can use the try...catch block, finally block, throw, and throws keyword to handle exceptions in Java. In this tutorial, we will learn about Java exception handling with the help of examples.
Exception handling is one of the most important feature of java programming that allows us to handle the runtime errors caused by exceptions. In this guide, you will learn what is an exception, types of it, exception classes and how to handle exceptions in java with examples.
What Is an Exception? An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions. The Catch or Specify Requirement. This section covers how to catch and handle exceptions. The discussion includes the try, catch, and finally blocks, as well as chained exceptions and logging.
