Listening and Logging Ant Output in Groovy

groovy-logo

In the comments section of my post Executing Ant Build File Targets from Groovy, CRC recently asked, “I’ve used your script and it seems to work but I could’t see any output at the console (I’m calling a echo task in build.xml), why?” This is a great question and one that I feel is better answered in a post than ...

Dozer: Mapping JAXB Objects to Business/Domain Objects

java-interview-questions-answers

Dozer is an open source (Apache 2 license) "Java Bean to Java Bean mapper that recursively copies data from one object to another." As this description from its main web page states, it is used to map two JavaBeans instances for automatic data copying between the instances. Although these can be any of the many types of JavaBeans instances, I ...

More Common Red Flags in Java Development

java-logo

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 “code ...

Uncompressing 7-Zip Files with Groovy and 7-Zip-JBinding

groovy-logo

This post demonstrates a Groovy script for uncompressing files with the 7-Zip archive format. The two primary objectives of this post are to demonstrate uncompressing 7-Zip files with Groovy and the handy 7-Zip-JBinding and to call out and demonstrate some key characteristics of Groovy as a scripting language. The 7-Zip page describes 7-Zip as “a file archiver with a high ...

Native Java Packaging with NetBeans 7.4

netbeans-logo

One of the new features of NetBeans 7.4 that made the “NetBeans 74 NewAndNoteworthy” page is “Native Packaging,” which is described on that page as “JavaSE projects now support creation of native bundles taking use of the native packaging technology provided by JavaFX.” I will use a very simple example to demonstrate this native packaging functionality in NetBeans 7.4. The ...

Too Many Parameters in Java Methods, Part 8: Tooling

java-logo

The first seven posts of my series of dealing with too many parameters expected in Java methods focused on alternative approaches to reduce the number of parameters a method or constructor expects. In this eighth post in the series, I look at tools that help identify cases where too many parameters may exist and tools that help deal with that ...

Too Many Parameters in Java Methods, Part 7: Mutable State

java-logo

In this seventh post of my series on addressing the issue of too many parameters in a Java method or constructor, I look at using state to reduce the need to pass parameters. One of the reasons I have waited until the 7th post of this series to address this is that it is one of my least favorite approaches ...

Too Many Parameters in Java Methods, Part 6: Method Returns

java-logo

In the current series of posts I am writing on reducing the number of parameters required to call Java methods and constructors, I have focused so far on approaches that directly affect the parameters themselves (custom types, parameters objects, builder pattern, method overloading, and method naming). Given this, it might seem surprising for me to devote a post in this ...

Too Many Parameters in Java Methods, Part 5: Method Naming

java-logo

In my previous post (Part 4 of my series on dealing with too many parameters in Java methods), I looked at method overloading as one approach to providing clients with versions of methods or constructors requiring fewer parameters. I described some disadvantages of that approach and suggested that breaking loose from method overloading to use differently named methods could at ...

Too Many Parameters in Java Methods, Part 4: Overloading

java-logo

One of the problems with expecting too many parameters to be passed to a Java method is that it is more difficult for the client of that method to be determine that they are passing the appropriate values in the appropriate order. In previous posts, I have described how custom types, parameters objects, and builders can be used to address ...
