Mastering Java is no small feat. Its extensive class libraries contain a wide array of capabilities and nuances, many of which are lost on the average developer. Those who have mastered the language can have a significant positive impact on your team's productivity and on your system's performance. Here are some targeted questions to help identify true masters of the language.
Java is one of the most portable languages available at a developer’s disposal. It’s possible for a great Java developer to build a highly distributed web application, a sophisticated desktop application, or even a powerful mobile application running on a handheld device. With the power of the Java Virtual Machine behind the platform, sometimes a talented developer is all it takes to build a robust, secure, and efficient application.
With Java developers being some of the most sought-after talent in the industry, it is particularly difficult to attract expert candidates with a generic job advertisement. To ensure that you hire an expert Java developer, there must be a very thorough interview process; however, the search begins with a great job ad. This article will provide you with a sample Java developer job description that will help you write the perfect job ad, and assure that you find and hire the person that matches your specific needs.
