**As a general rule, an exception is defined as an occurrence that occurs while a program is running and disturbs the flow of instructions. Any time an application encounters an exception, it's because an error has occurred and there's no way to fix it except to terminate the program.
Why is it necessary to deal with Java exceptions?
Exception handling in Java is critical because it ensures that the program continues to run normally even in the face of unexpected events. As a result, applications may stop working or requests may fail if Java exceptions are not handled. Customers may get dissatisfied and, if this occurs on a regular basis, you may lose them.
Especially if the user's data is lost, a crash of your application when they are in the middle of anything critical is the worst-case scenario. To avoid the program from abruptly failing and losing data, it is essential to manage Java exceptions. A sudden system crash can be caused by a variety of factors, including inaccurate or unexpected data entry. The integrity of the database would be compromised if we tried to add two users with the same IDs to the database.
Many of the Java exceptions that a piece of code is capable of throwing may be predicted by developers. In order to gently recover from these exceptions, it is best to explicitly manage them. Exceptions can be handled in a variety of ways, starting with particular ones and progressing to more general ones. Unhandled Java exceptions are those that can't be predicted in advance. It's a good idea to record these as well, so that you can recover gracefully. Your development team will have better visibility into code quality and root causes if Java exceptions are tracked centrally.
Exception Tracking
Regardless of how skillfully you build your software, most software engineers will agree that exceptions will occur. It's impossible to know exactly what the runtime environment of your customer will be like in advance. All events are recorded in the app log file by default. You may travel back in time and see exactly what happened before you encountered the Java exception by looking at the log file, which is like a time machine for developers (or analysts).
Using a log file for small-scale applications is a simple task. When it comes to serving large numbers of requests per second, corporate apps can do so. This makes manual analysis excessively time-consuming since mistakes and their causes might be buried in the commotion of other data. This is where error tracking software may help, by grouping duplicates and presenting a summary view of the top and most recent Java problems. Error monitoring software can. As a bonus, contextual data may be collected and organized in a way that is both quicker and more convenient than going through logs individually.
How to deal with Java exceptions.
First, let's go over the fundamentals of exception handling in Java. Error handling can be simplified to the try-catch approach. There are one or more catch blocks for any Java exceptions thrown by the code you want to run.The method is capable of catching all Java exceptions. The simplest way to deal with exceptions is with this mechanism
