The Reference API in Java is a way to add a level of indirection. Indirection is the ability to reference something using a name, reference, or container instead of the value itself. It is an important principle in computer science.
Welcome to 2021! I hope it is going to be a productive, successful and happy year for all of us. I don’t like the term “New Year’s resolutions”. It reminds me of all the usual things that millions of people put on their list every year. Get fit, lose weight,

The Reflection API is a way to find out about the internals of a Java class – its fields, constructors, methods and annotations. In this article we look at the Reflection API class and some example code.
Sometimes we need to decompile Java source code. This is useful to retrieve lost source code, or to see what the compiler has automatically generated. We conduct a quick experiment using two Java decompilers.
There’s a reason you pay for plastic shopping bags. It is to protect the environment. Durable shopping bags can be re-used, and don’t pollute our oceans and landfills. Re-use is a good thing – and not just for the environment. We know that code re-use is important. And that also
Cross-site request forgery (CSRF or XSRF) is also known as “Sea Surf” or “Session Riding”. But unlike real surfing, it’s got nothing to do with waves, water or the beach.
The debug compiler flag is a way to get the compiler to insert more debugging information. When we debug Java code, we want as much information about our code as possible.
Last week I wrote about Cross-Site Scripting, and the serious consequences it can have. According to OWASP, XSS affects about two thirds of all applications. That statistic should scare you! Now that I have your attention, let’s look at how we can stop XSS.
There’s probably nothing programmers hate more than documenting their code. Fortunately for Java developers, help is at hand. The JavaDoc tool generates HTML documentation from comments we write in our code.
