Item 90: Java Best Practices - Consider serialization proxies instead of serialized instances

Fair Use Sources

Java Best Practices: Based on Effective Java.

Java Creating and Destroying Objects:

• 1: Consider static factory methods instead of constructors
• 2: Consider a builder when faced with many constructor parameters
• 3: Enforce the singleton property with a private constructor or an enum type
• 4: Enforce noninstantiability with a private constructor
• 5: Prefer dependency injection to hardwiring resources
• 6: Avoid creating unnecessary objects
• 7: Eliminate obsolete object references
• 8: Avoid finalizers and cleaners
• 9: Prefer try-with-resources to try-finally

Java Methods Common to All Objects:

• 10: Obey the general contract when overriding equals
• 11: Always override hashCode when you override equals
• 12: Always override toString
• 13: Override clone judiciously
• 14: Consider implementing Comparable

Java Classes and Interfaces:

• 15: Minimize the accessibility of classes and members
• 16: In public classes, use accessor methods, not public fields
• 17: Minimize mutability
• 18: Favor composition over inheritance
• 19: Design and document for inheritance or else prohibit it
• 20: Prefer interfaces to abstract classes
• 21: Design interfaces for posterity
• 22: Use interfaces only to define types
• 23: Prefer class hierarchies to tagged classes
• 24: Favor static member classes over nonstatic
• 25: Limit source files to a single top-level class

Java Generics:

• 26: Don’t use raw types
• 27: Eliminate unchecked warnings
• 28: Prefer lists to arrays
• 29: Favor generic types
• 30: Favor generic methods
• 31: Use bounded wildcards to increase API flexibility
• 32: Combine generics and varargs judiciously
• 33: Consider typesafe heterogeneous containers

Java Enums and Annotations:

• 34: Use enums instead of int constants
• 35: Use instance fields instead of ordinals
• 36: Use EnumSet instead of bit fields
• 37: Use EnumMap instead of ordinal indexing
• 38: Emulate extensible enums with interfaces
• 39: Prefer annotations to naming patterns
• 40: Consistently use the Override annotation
• 41: Use marker interfaces to define types

Java Lambdas and Streams:

• 42: Prefer lambdas to anonymous classes
• 43: Prefer method references to lambdas
• 44: Favor the use of standard functional interfaces
• 45: Use streams judiciously
• 46: Prefer side-effect-free functions in streams
• 47: Prefer Collection to Stream as a return type
• 48: Use caution when making streams parallel

Java Methods:

• 49: Check parameters for validity
• 50: Make defensive copies when needed
• 51: Design method signatures carefully
• 52: Use overloading judiciously
• 53: Use varargs judiciously
• 54: Return empty collections or arrays, not nulls
• 55: Return optionals judiciously
• 56: Write doc comments for all exposed API elements

Java General Programming:

• 57: Minimize the scope of local variables
• 58: Prefer for-each loops to traditional for loops
• 59: Know and use the libraries
• 60: Avoid float and double if exact answers are required
• 61: Prefer primitive types to boxed primitives
• 62: Avoid strings where other types are more appropriate
• 63: Beware the performance of string concatenation
• 64: Refer to objects by their interfaces
• 65: Prefer interfaces to reflection
• 66: Use native methods judiciously
• 67: Optimize judiciously
• 68: Adhere to generally accepted naming conventions

Java Exceptions:

• 69: Use exceptions only for exceptional conditions
• 70: Use checked exceptions for recoverable conditions and runtime exceptions for programming errors
• 71: Avoid unnecessary use of checked exceptions
• 72: Favor the use of standard exceptions
• 73: Throw exceptions appropriate to the abstraction
• 74: Document all exceptions thrown by each method
• 75: Include failure-capture information in detail messages
• 76: Strive for failure atomicity
• 77: Don’t ignore exceptions

Java Concurrency:

• 78: Synchronize access to shared mutable data
• 79: Avoid excessive synchronization
• 80: Prefer executors, tasks, and streams to threads
• 81: Prefer concurrency utilities to wait and notify
• 82: Document thread safety
• 83: Use lazy initialization judiciously
• 84: Don’t depend on the thread scheduler

Java Serialization:

• 85: Prefer alternatives to Java serialization
• 86: Implement Serializable with great caution
• 87: Consider using a custom serialized form
• 88: Write readObject methods defensively
• 89: For instance control, prefer enum types to readResolve
• 90: Consider serialization proxies instead of serialized instances
