In contrast, the techniques in this book will teach developers to decompile, patch, and reverse-engineer applications, to better understand their implementation, and to work more efficiently with applications developed by others. Covert Java offers a unique approach to solving common Java problems, from combating confusion in the code, to patch the core classes to change the desired function of the application. Each chapter focuses on techniques that solve a specific problem - outlining the problem, suggesting solutions, and then suggest additional ideas for developers to test this technique.
