Processing Java Annotations Using Reflection
Keyhole SoftwareSeptember 24th, 2014Last Updated: September 24th, 2014 In my previous article covering Java Annotations, I outlined a recent use case and provided you with some examples of custom annotations and how they might be used. In this article, I’m going to take that a step further and give you a few examples of custom annotations and how you would process these custom annotations using th
More Common Red Flags in Java Development
Dustin MarxDecember 6th, 2013Last Updated: December 6th, 2013 In the post Common Red Flags in Java Development I looked at some practices that are not necessarily wrong or incorrect in and of themselves, but can be indicative of potentially greater problems. These “red flags†are similar to the concept of “code smells†and some of the particular “red flags†I cite in this post have been called “co
Java Debugger - The Definitive List of Tools
Iris ShoorDecember 6th, 2013Last Updated: December 6th, 2013 Java debugging is a complex space. There are many types of debuggers, and numerous tools to choose from. In this page, we’ll cover the differences between 7 types of debuggers, and review the major tools in each category to help you choose the right tool for the right job. Here are the types of debuggers we cover: CLI debuggersIDE debugg
Java Nested Transaction using ThreadLocal in POJO
Baskaran ChinnusamyDecember 8th, 2013Last Updated: December 6th, 2013 Mostly nested transaction was implemented using EJB , now we try to implement the nested transaction on POJO. Here we have used the feature of ThreadLocal. Understanding Nested TransactionTransactions can be nested one inside another. So the inner transaction or outer transaction can be rollback or commit without affecting the
Anatomy of a Java Decompiler
Attila Mihaly BalazsDecember 14th, 2013Last Updated: December 14th, 2013 A decompiler, simply put, attempts to reverse the transformation of source code to object code. But there are many interesting complexities—Java source code is structured; bytecode certainly isn’t. Moreover, the transformation isn’t one-to-one: two different Java programs may yield identical bytecode. We need to apply heurist
lambdas and side effects
Peter LawreySeptember 22nd, 2014Last Updated: September 22nd, 2014 OverviewJava 8 has added features such as lambdas and type inference. This makes the language less verbose and cleaner, however it comes with more side effects as you don’t have to be as explicit in what you are doing. The return type of a lambda mattersJava 8 infers the type of a closure. One way it does this is to look at the ret
5 Error Tracking Tools Java Developers Should Know

Garbage Collection: increasing the throughput
Nikita Salnikov TarnovskiSeptember 23rd, 2014Last Updated: September 23rd, 2014 The inspiration for this post came after stumbling upon “Pig in the Python†definition in the memory management glossary. Apparently, this term is used to explain the situation where GC repeatedly promotes large objects from generation to generation. The effect of doing so is supposedly similar to that of a python swal
java.net.Inet4Address Example - Java Code Geeks
Aldo ZiflajSeptember 26th, 2014Last Updated: September 22nd, 2014 In this example we will discuss about Inet4Address and its usage. Inet4Address represents an Internet Protocol version 4 (IPv4) address. Inet4Address is a subclass of InetAddress class, which represents either a 32-bit or 128-bit unsigned number used as an IP, the lower-level protocol on which protocols like UDP and TCP are built. T
java.util.Locale Example - Java Code Geeks
In this article we will discuss about the Locale class from java.util package. The Locale is used to make the system relevant and usable for the users from different cultures. In other words, it is used to customize the system for different people of different region, culture and language. A Locale object represents a specific geographical, political, or cultural region. Let’s discuss about the Lo
