How to Specify and Handle Exceptions in Java

Errors happen all the time in the software world. It might be an invalid user input, an external system not responding, or a simple programming error. In all these situations, the errors occur at runtime, and the application needs to handle them. Otherwise, it crashes and can’t process further requests. Java provides a powerful exception handling mechanism that allows you to handle the exceptional event where it occurred or in one of the higher methods in the call stack.

What is an Unhandled Exception and How to Find Them

In the world of programming, exceptions are inevitable. They represent unexpected or exceptional events that can occur during the execution of a program. While some exceptions might be anticipated and handled gracefully, others might be unexpected, leading to application crashes or unexpected behavior. This guide delves into the nuances of exceptions in C#, focusing on the importance of handling an unhandled exception and the tools available for the same.

How Log4J2 Works: 10 Ways to Get the Most Out Of It

Log4j2 is the updated version of the popular and influential log4j library, used extensively throughout the Java ecosystem for so many years. Version 2.x keeps all the logging features of its predecessor and builds on that foundation with some significant improvements, especially in the area of performance. And of course, given how instrumental logging is for any application, both for audit and debugging purposes, choosing a solid logging library is quite an important decision.

PHP Try Catch: Basics & Advanced PHP Exception Handling Tutorial

When PHP version 5 was released, it incorporated a built-in model to catch errors and exceptions. Handling errors in PHP with try catch blocks is almost the same as handling errors in other programming languages. When a PHP exception is thrown, the PHP runtime looks for a catch statement that can handle that type of exception. It will continue checking the calling methods up the stack trace until a catch statement is found.

What are Microservices? Code Examples, Best Practices, Tutorials and More

Microservices are increasingly used in the development world as developers work to create larger, more complex applications that are better developed and managed as a combination of smaller services that work cohesively together for more extensive, application-wide functionality. Tools such as Service Fabric are rising to meet the need to think about and build apps using a piece-by-piece methodology that is, frankly, less mind-boggling than considering the whole of the application at once.
