![]() The idea is that annotations can tell tools how to generate new code, transform code, or behave at run-time. Used this way, annotations act as a form of machine-checked documentation.Īnnotations have also played a central role in making developers more productive through techniques such as metaprogramming. The Java compiler then uses the annotations to warn the developer if the program doesn't match their intentions. ![]() In response, the annotation was introduced so that developers could document methods as overriding a superclass method. Eliminating a method call in this manner can introduce a defect or security vulnerability. If you're not careful, when modifying a method declaration, you might cause a subclass method to not be called. In large projects with non-trivial inheritance hierarchies, it's hard to keep track of which implementation of a method will execute at runtime. Consider the annotation, which was introduced back in Java 1.5. The same story is playing out in every other industry.Īs a Java programmer, you're probably already using annotations to improve the quality of your software. Sacrificing security or quality, however, is not an option: simply confusing percentage points and basis points can have serious consequences. In the financial industry, our fluctuating market and regulatory environments mean that time to market is more important than ever. Microsoft Azure supports your workload with abundant choices, whether you're working on a Java app, app server, or framework.
