Many current web applications rely on near-frictionless and simultaneous access to numerous API providers' Web APIs. However, the web's default is to prohibit such "loose" behaviour, much like a firewall that blocks access to untrusted parties in the name of security. That default, thankfully, can be safely altered. Before doing so, however, it is necessary for both Web application developers and API providers to understand the concepts of Cross-Origin Resource Sharing (CORS).

Symbol tables are an important data structure created and maintained by compilers to store information associated with identifiers . A simplified representation of a symbol table entry (or simply, a symbol) in Java has the following format: .

Java is an object-oriented programming language. It supports a variety of techniques, including exception handling. This Java feature allows developers to control exception-related runtime issues. In Java, an exception is an event that happens during the execution of a program and prevents the program's instructions from flowing normally. Exceptions are bugs or errors that we don't want and that prevent our application from running normally. In this article, we are discussing exceptions in Java.

Data and information are the main currency of the 21st century. When managing applications, we have to deal with reams of data and store it for future use, either in our file system, in the memory of the application or in designated data management apps, also known as databases.

Since the time we are born, we are told not to judge a book by its cover. Naturally, this principle has never been meant to apply solely to books. The phrase is a way of reminding people that the appearance of anything, whether it be a book, app, or even a person, doesn’t necessarily indicate whether it’s valuable or not. To some degree, this can be an important lesson to remember. However, there are instances when physical appearance can tell us something about a business or individual.

Having an online presence is important, especially in this day and age. Nearly everything and everyone has gone digital and the first step anyone takes when trying to discover new businesses and services is to ‘Google it’. While social media and other such platforms have their place in digital marketing, nothing beats the exclusivity, control and professionalism that having your own website gives you.

Error handling is one section of our job that we tend to neglect, especially when working on something new, interesting, or something we just need to get working. We’ll handle errors later, we say — and that’s often a big lie. But that’s not even the worst part. The problem comes when we decide to ‘quickly’ add some code to handle our errors and completely forget about the importance and relevance of a properly constructed error message.

Authorization (not to be confused with authentication) is vital to every application but often isn’t given much thought before implementation. The IETF Site Security Handbook defines authorization as: So, in short, authorization is about defining access policies and scoping. For example, consider a platform like Github.

Consumer demand for a digital, connected insurance experience is on the rise. But with disparate legacy systems in place that make it difficult to share data and make informed, real-time decisions, insurance companies are finding themselves in need of new technology to streamline their customer journey.

Software development is a series of trial and error. It takes a conscientious effort and a large amount of time to create a product that meets technical specifications and user requirements. That is why repeated software testing is a significant part of the process, as it allows developers to take notes and improve the product each time. Catching software issues early on can save a company a lot of time and money.

Errors happen in every application. Devs have to decide: do you write code to handle the error? Suppress it? Notify the user? Report it to the team? In this article, Ayo Isaiah walks us through every aspect of the JavaScript error system. He'll show us how to work with errors and discuss appropriate choices for real-world scenarios.

In modern application architecture and development, there has been a push from monolithic applications towards microservices. This has made microservices frameworks (micro-frameworks) very popular since they make it easier to prototype, design and build microservices applications. Spring Boot and Quarkus are both very popular microservices frameworks for building cloud native Java applications.

At its most basic level, DevOps—a combination of development and operations—refers to a set of practices that streamline application development at every stage, from building and testing to deploying and monitoring. DevOps largely aims to break down silos and improve collaboration for teams looking to increase agility without compromising on software quality. Unfortunately, traditional high-code methods of development present a few challenges to successful DevOps transformations.
