This book presents Java implementations of algorithms commonly found in the C++ Standard Template Library, alongside numerous other practical algorithms not included in that library. The authors, Cay S. Horstmann and Gary Cornell, leverage their expertise in Java programming to provide ready-to-use code for everyday programming challenges. The work focuses on providing tangible solutions for tasks such as encryption, text manipulation, and graph traversal.

This technical reference is likely regarded as a valuable resource for Java developers seeking to implement standard algorithms. The inclusion of both STL-equivalent and supplementary algorithms suggests a comprehensive approach to practical problem-solving in Java. Its focus on day-to-day programming tasks indicates it is aimed at developers needing efficient, ready-made solutions.
