The book “Java by Comparison” by Simon Harrer, Jörg Lenhard, and Linus Dietz , promises the reader to become a “Java Craftsman” through the study of 70 examples. The book is published by The Pragmatic Bookshelf.

Each “example” is structured as a before-and-after comparison. It’s best to illustrate that with, well, an example:

Return Boolean Expressions Directly

Before:

boolean isValid() {
 if (missions < 0 || name == null || name.trim().isEmpty()) {
 return false;
 } else {
 return true;
 }
}

After:
