Secrets Of The Masters: Core Java Job Interview Questions

JDJ's Enterprise Editor, Yakov Fain (pictured) writes: If you are planning to hit the job market,  you may need to refresh some of the Java basic terms and techniques to prepare yourself for a technical interview. Let me offer you some of the core Java questions that you might expect during the interviews.  For  most questions  I’ve provided only  short  answers to encourage further research.  I have included only  questions for mid (*) and senior level (**) Java developers.

A Cup of AJAX? Nay, Just Regular Java Please

These days everyone is talking about AJAX. It’s supposed to be a cool way of creating Web applications. The idea is noble: instead of rendering an entire HTML page on each little change on the page, it’s much better to send an asynchronous request that will  get the data for you and refresh only the relevant portion of the screen.

Now a good designer comes with N... (more)

Teaching Kids Programming: Even Younger Kids Can Learn Java

My solution to the problem? I've written my own e-book on it: Java Programming for Kids, Parents and Grandparents. Dave became my first kid student and this has helped me a lot to understand the mentality of the little people. This is what I've learned while working on this project: Most of the programming tasks require minimal knowledge of arithmetic and algebra skills. To start programming, a kid needs to understand what x = y+2 means. Another important concept to understand is an if statement.   Kids develop the abstract reasoning abilities by the fourth-fifth grade, and they... (more)
