Kent Beck’s “Implementation patterns” is the first book that I bought in this year. Its main concern is how to write better code that is readable and understandable, and it also touchs fundamentals of software design especially OOP. One of the book’s keywords is “intention”. Its strengths lie in being well-structured, easy to understand and thin.

However it is not a pioneeering book like DP of GoF; it doesn’t address something really new. That makes me a little disppointed because I have expected it would tell me lots of stuffs that I didn’t realize before. It is like a well-documented wikipedia in that sense.

The title of book need to be changed to “Implementation patterns in Java”. It is not just because example code of the book is written in Java but because some topics are very specific to Java so that these topics are not concerns of Non-Java developers.

The annotation, already a must in Junit4, is adopted by Swing (JSR 296).

It is becoming a trend.

When I installed PMD plugin to my Eclipse and tested the plugin, I found that following rules appear in “Effective Java” by Joshua.

* OverrideBothEqualsAndHashcode
* FinalizeDoesNotCallSuperFinalize
* ConstructorCallsOverridableMethod
* ProperCloneImplementation
* CloneThrowsCloneNotSupportedException
* CloneMethodMustImplementCloneable
* ReplaceVectorWithList
* ReplaceHashtableWithMap
* UseArrayListInsteadOfVector
* ReturnFromFinallyBlock
* EmptyCatchBlock
* ExceptionAsFlowControl
