Determining Presence of Characters or Integers in String with Guava CharMatcher and Apache Commons Lang StringUtils

A recent Reddit post asked the question, “Is there a predefined method for checking if a variable value contains a particular character or integer?” That question-based title was also asked a different way, “A method or quick way for checking if a variable contains any numbers say or (‘x’,2,’B’) like a list?” I am not aware of any single method ...

java-interview-questions-answers

This post looks at mapping JAXB objects to business domain objects with Orika. Earlier this month, I covered the same mapping use case using reflection-based Dozer. In this post, I’ll assume the same example classes need to be mapped, but they will be mapped using Orika instead of Dozer. Dozer and Orika are intended to solve the same type of ...

More Common Red Flags in Java Development

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 ...

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

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 ...
