Object-Oriented Programming: From Problem Solving to Java [With CDROM]

If you need to practice your Java object oriented coding, try using Garrido's book. He gives many example problems in pseudocode. These are very well suited to you taking them and manually translating that pseudocode into Java. Think of this perhaps as similar to a Schaum's Outline book of problem sets. Of course, you can also do the obvious of learning the object oriented aspects of Java from the book. But basically any book on teaching the general properties of Java tends to cover this to some fashion, since Java is fully object oriented. Garrido's book is a little more distinctive in having a collection of problems in pseudocode put right in front of you.
