Data Abstraction And Problem Solving With Java

The Third Edition of Data Abstraction and Problem Solving with Java: Walls and Mirrors employs the analogies of Walls (data abstraction) and Mirrors (recursion) to teach Java programming design solutions, in a way that beginning students find accessible. The book has a student-friendly pedagogical approach that carefully accounts for the strengths and weaknesses of the Java language. With this book, students will gain a solid foundation in data abstraction, object-oriented programming, and other problem-solving techniques.

The book teaches two things. Algorithms that are very useful in computing. And how these can be coded in Java.
The explanation of the algorithms requires a reasonable amount of mathematical sophistication on your part. They all relate to discrete maths, and cover topics like sorting, random number generation and graphs. The complexity of the discussion is less than that in Knuth's "Art of Computer Programming". Perhaps more akin to Sedgewick or Aho's algorithms texts. There is a fair amount of abstraction that you'll have to deal with.
