内容説明
For courses in Java Programming-Intermediate/Advanced.
This text builds upon basic examples written in Java to present more complex topics and methods of improving the performance of Enterprise applications. The authors' first-hand experience at IBM's SanFrancisco Project provides students with deep insight into the use of Java for business needs-and guidance to help avoid performance pitfalls.
