Solving OutOfMemoryError (part 4) - memory profilers | Plumbr

http://plumbr.eu/blog/solving-outofmemoryerror-memory-profilers It is about time to continue our Solving OutOfMemoryError blog post series. In retrospect, so far we have covered: Part 1 described the Story of solving an OutOfMemoryError through the eyes of a Developer , Part 2 explained how the Ops usually tackle the OutOfMemoryError problem , and Part 3 started looking at where to start solving the OutOfMemoryError . A couple of next posts will now look at the existing tools that you can use to find a Java memory leak. Our past experience, which is supported by a quick search on Google and Stackoverflow, shows that the first set of tools people tend to jump to when solving memory problems in production is memory profilers.

Strings in switch statements In the JDK 7 release, you can use a String object in the expression of a switch statement: public String getTypeOfDayWithSwitchStatement(String dayOfWeekArg) {
I recently worked on a quite complex project mixing many Java EE 6 technologies (such as JPA, JAXB, JMS, JTA, JAX-RS, etc…). For productivity and planning reasons, the prototyped application was designed as a standalone pure Spring application. When the development of the real application started, we re-challenged our initial choice (i.e. Spring v3) and analyzed the interest of switching to a Java EE 6 app server like GlassFish or JBoss.

Java Interview: Coding Questions and Answers

Interviewing for a job can be stressful, but if there is one thing that can add more complexity to the interview process, it would be the technical interview. Nothing strikes fear in the heart of developers faster than the thought of sweating hands and an interview’s stare as you struggle through a coding problem on a whiteboard. This is the stuff of nightmares.
Below is a list of some tools that can help you examine your Java source code for potential problems: 1. PMD from http://pmd.sourceforge.net/ License: PMD is licensed under a “BSD-style” license PMD scans Java source code and looks for potential problems like: * Possible bugs – empty try/catch/finally/switch statements * Dead code – unused local variables, parameters and private methods * Suboptimal code – wasteful String/StringBuffer usage * Overcomplicated expressions – unnecessary if statements, for loops that could be while loops * Duplicate code – copied/pasted code means copied/pasted bugs
