Coding and testing are often consideredseparate areas of expertise. In this comprehensive guide, author and Javaexpert Scott Oaks takes the approach that anyone who works with Java should beequally adept at understanding how code behaves in the JVM, as well as thetunings likely to help its performance.
You’ll gain in-depth knowledge of Java application performance, using the JavaVirtual Machine (JVM) and the Java platform, including the language and API.Developers and performance engineers alike will learn a variety of features,tools, and processes for improving the way Java 7 and 8 applications perform.
Apply four principles for obtaining the best results from performance testing
Use JDK tools to collect data on how a Java application is performing
Understand the advantages and disadvantages of using a JIT compiler
Tune JVM garbage collectors to affect programs as little as possible
Use techniques to manage heap memory and JVM native memory
Maximize Java threading and synchronization performance features
Tackle performance issues in Java EE and Java SE APIs
