There is the book Java how program by Dietel and there is an early object version and late Version what’s the difference between early and late

The early object version of Java How to Program by Dietel was written for Java versions 1.0-1.2 and focused on traditional procedural programming with some object-oriented concepts introduced later. The late object version, on the other hand, was written for Java versions 5 and 6 and placed a stronger emphasis on object-oriented programming from the beginning, with a focus on modern programming practices and technologies. The late object version also includes more advanced topics such as generics and concurrency.
