オラクル認定資格教科書 Javaプログラマ Silver SE11（試験番号1Z0-815）

**** The "Java Programmers Silver SE11 (Exam Number 1Z0-815)" book garners a generally positive reception among customers, particularly as a resource for those preparing for the Java certification exam. Users find it beneficial as a supplementary textbook alongside other resources like the infamous "black book." Many have noted the book’s capability to cover essential Java concepts adequately, and the inclusion of additional problems not found in other preparatory materials is especially valued. This variety enhances practice and promotes a deeper understanding of the subject matter. However, potential readers should be aware of some shortcomings. A common critique is the formatting of the code, which some customers find challenging due to a lack of proper line breaks, making it harder to read. Furthermore, the explanations accompanying the practice problems might not be as comprehensive as those found in the black book, particularly for beginners or those without established programming backgrounds. The book is recommended more for those with some programming experience since it cuts out redundancy. It provides a wealth of problems, enabling readers to engage in rigorous practice—something that serious candidates find beneficial. However, for absolute novices, the use of specific jargon and less detailed explanations can be a hurdle. Additionally, while the book is focused on diving deeper into Java, it’s suggested that pairing it with other resources will yield the best results for exam preparation. In summary, this book is seen as a strong asset for those looking to deepen their knowledge of Java programming while also preparing for the certification exam, but it may pose challenges for complete beginners. **
