Hi guys, I am happy to tell you that I am moving to the open source world. And Java is the 1st language I have chosen for this migration. It's a nice chance to read some great books like "Effective Java 2nd Edition" and share the note for what I learned from it with you just as what I did before with CSharp. Here is the index of the notes. Hope you like it :)

Part I Creating and Destroying Object
Effective Java 01 Consider static factory methods instead of constructors
Effective Java 02 Consider a builder when faced with many constructor parameters
Effective Java 03 Enforce the singleton property with a private constructor or an enum type
Effective Java 04 Enforce noninstantiability with a private constructor
Effective Java 05 Avoid creating unnecessary objects
Effective Java 06 Eliminate obsolete object references
Effective Java 07 Avoid finallizers
Part II Methods common to all Objects
Effective Java 08 Obey the general contract when overriding equals
Effective Java 09 Always override hashCode when you override equals
Effective Java 10 Always override toString() method
Effective Java 11 Override clone judiciously
Effective Java 12 Consider implementing Comparable
Part III Classes and Interfaces
Effective Java 13 Minimize the accessibility of classes and members
Effective Java 14 In public classes, use accessor methods, not public fields
Effective Java 15 Minimize mutability
Effective Java 16 Favor composition over inheritance
Effective Java 17 Design and document for inheritance or else prohibit it
Effective Java 18 Prefer interfaces to abstract classes
Effective Java 19 Use interfaces only to define types

Effective Java 29 Consider typesafe heterogeneous containers
Part V Enums and Annotations
Effective Java 30 Use Enums instead of int constants
Effective Java 31 Use instance fields instead of ordinals
Effective Java 32 Use EnumSet instead of bit fields
Effective Java 33 Use EnumMap instead of ordinal indexing

Effective Java 36 Consistently use the Override annotation
Effective Java 37 Use marker interfaces to define types
Part VI Methods
Effective Java 38 Check parameters for validity
Effective Java 39 Make defensive copies when needed
Effective Java 40 Design method signatures carefully
Effective Java 41 Use overloading judiciously
ffective Java 42 Use varargs judiciously
Effective Java 43 Return empty arrays or collections, not nulls
Effective Java 44 Write doc comments for all exposed API elements
Effective Java 45 Minimize the scope of local variables
Part VII General Programming
Effective Java 46 Prefer for-each loops to traditional for loops
Effective Java 47 Know and use the libraries
Effective Java 48 Avoid float and double if exact answers are required
Effective Java 49 Prefer primitive types to boxed primitives
Effective Java 50 Avoid strings where other types are more appropriate
Effective Java 51 Beware the performance of string concatenation
Effective Java 52 Refer to objects by their interfaces
Effective Java 53 Prefer interfaces to reflection
Effective Java 54 Use native methods judiciously
Effective Java 55 Optimize judiciously
Effective Java 56 Adhere to generally accepted naming conventions
Part VIII Exceptions
Effective Java 57 Use exceptions only for exceptional conditions
Effective Java 58 Use checked exceptions for recoverable conditions and runtime exceptions for programming errors
Effective Java 59 Avoid unnecessary use of checked exceptions
Effective Java 60 Favor the use of standard exceptions
Effective Java 61 Throw exceptions appropriate to the abstraction
Effective Java 62 Document all exceptions thrown by each method
Effective Java 63 Include failure-capture information in detail message
Effective Java 64 Strive for failure atomicity
Effective Java 65 Don't ignore exceptions
Part IX Concurrency
Effective Java 66 Synchronize access to shared mutable data
Effective Java 67 Avoid excessive synchronization
Effective Java 68 Prefer executors and tasks to threads
Effective Java 69 Prefer concurrency utilities to wait and notify
Effective Java 70 Document thread safety
Effective Java 71 Use lazy initialization judiciously
Effective Java 72 Don't depend on the thread scheduler
Effective Java 73 Avoid thread groups
Part X Serialization
Effective Java 74 Implement Serializable judiciously
Effective Java 75 Consider using a custom serialized form
Effective Java 76 Write readObject methods defensively
Effective Java 77 For instance control, prefer enum types to readResolve
Effective Java 78 Confider serialization proxies instead of serialized instances
