Java Professional Tuning and Advanced Diagnostics
(JPTO, Live Instructor-Led Training, 5 days)


Description

If you still believe that Java is slow, you need to take this course. This SETC certified course dispels the myth that Java is slow and bloated. Our experienced Java trainers will crack open the hood of the JVM so that developers understand what may slow down a Java application (hint: garbage collection is not at fault) and how to write blazingly fast code. Starting with profiling and performance tuning, the course explores in detail how to take advantage of the Java programming language, followed by effecient use of the Class Library, including text manipulation, input/outputs and collections. The course goes beyond Java SE and explores how to ensure that an Enterprise Java application is a fast as necessary.
