In C++, destructors are the normal way to reclaim the resources associated with an object, a necessary counterpart to constructors. Miraculously the new edition still is no thicker than its predecessor, which is due to the rather cheap print, i'm afraid. The best way to write a robust, responsive, portable program is to ensure that the average number of, Thread priorities are among the least portable features of the Java platform, Thread groups do not provide any security functionality, Prior to release 1.5, there was one small piece of functionality that was available only with the ThreadGroup API the, incompatible changes after deserialization lead to failure, Because there is no explicit constructor associated with deserialization, it is easy to forget that you must ensure that it guarantees all of the invariants established by the constructors, Releasing new version of serialized class greatly improves number of test-cases need to be verified, Classes designed for inheritance should rarely implement, You should consider providing a parameterless constructor on nonserializable classes designed for inheritance, Do not accept the default serialized form without first considering whether it is appropriate, The default serialized form is likely to be appropriate if an object’s physical representation is identical to its logical content, Even if you decide that the default serialized form is appropriate, you often must provide a readObject method to ensure invariants and security, Before deciding to make a field nontransient, convince yourself that its value is part of the logical state of the object, Declare an explicit serial version UID in every serializable class you write.

Lately I’ve been learning Effective Java by Joshua Block. This highly readable book tells you how to use the Java programming language and its most fundamental libraries to best effect. When you mix primitives and boxed primitives in a single operation, the boxed primitive is auto-unboxed, Use boxed primitives as type parameters in parameterized types, Use boxed primitives when making reflective method invocations, Strings are poor substitutes for other value types (, Strings are poor substitutes for enum types, Strings are poor substitutes for aggregate types; to access individual fields you must parse string, Using the string concatenation operator repeatedly to concatenate n strings requires O(n^2) time, If appropriate interface types exist, then parameters, return values, variables, and fields should all be declared using interface types, If you depend on any special properties of an implementation, document these requirements where you declare the variable.

Press question mark to learn the rest of the keyboard shortcuts They take up thirty-three pages in the language specification [JLS, 15.12.1-3], Don’t use varargs for every method that has a final array parameter; use varargs only when a call really operates on a variable-length sequence of values, Every invocation of a varargs method causes an array allocation and initialization, Use overloaded methods with 2, 3, 4 params to cover most use-cases, otherwise use varargs, Zero-length arrays and empty collections are not performance problems, because they are immutable and only one instance could be used, To document your API properly, you must precede every exported class, interface, constructor, method, and field declaration with a doc comment, If a class is serializable, you should also document its serialized form, The doc comment for a method should describe succinctly the contract between the method and its client, With the exception of methods in classes designed for inheritance, the contract should say, Methods should document pre- and postconditions, side effects, thread safety, exceptions, The first “sentence” of each doc comment should be the summary description, When documenting a generic type or method, be sure to document all type parameters, When documenting an enum type, be sure to document the constants, When documenting an annotation type, be sure to document any members, The most powerful technique for minimizing the scope of a local variable is to declare it where it is first used, Nearly every local variable declaration should contain an initializer (, transforming (no access to index element to apply change), parallel iteration (needed few iterators and control locks), By using a standard library, you take advantage of the knowledge of the experts who wrote it and the experience of those who used it before you, If a flaw were to be discovered, it would be fixed in the next release, With using libraries you don’t have to waste your time writing ad hoc solutions to problems that are only marginally related to your work, Performance of standard libraries tends to improve over time, with no effort on your part, Libraries tend to gain new functionality over time, If performance is crucial, you don’t mind keeping track of the decimal point yourself, and the quantities aren’t too big, use.

Etwas ist schiefgegangen. Function objects are simulate functions in OOP Item 58: Prefer for-each loops to traditional for loops Item 59: Know and use the libraries Item 60: Avoid float and double if exact answers are required Item 61: Prefer primitive types to boxed primitives Item 62: Avoid strings where other types are more appropriate Item 63: Beware the performance of string concatenation As a rule, objects should not be accessed reflectively in normal applications at runtime, Create instances reflectively and access them normally via their interface or superclass, The Java Native Interface (JNI) allows Java applications to call native methods, which are special methods written in native programming languages such as C or C++, Access to platform-specific facilities such as registries and file locks, Access to libraries of legacy code, which could in turn provide access to legacy data, Used to write performance-critical parts of applications, Do not use native methods for improved performance, Applications using native methods have disadvantages, programs are not immune to memory corruption errors, Premature optimization is the root of all evil, Strive to write good programs rather than fast ones, Strive to avoid design decisions that limit performance, Consider the performance consequences of your API design decisions, Measure performance before and after each attempted optimization, Conventions should not be followed blinfly if long-held conventional usage dictates otherwise, Placing code inside a try-catch block inhibits certain optimizations that modern JVM implementations might otherwise perform, A well-designed API must not force its clients to use exceptions for ordinary control flow, Java provides three kinds of throwables: checked exceptions, runtime exceptions, and errors, Use checked exceptions for conditions from which the caller can reasonably be expected to recover, Unchecked exceptions indicate programming error and not needed to be handled, Errors indicated JVM problems and not needed to be handled at all, If catching exception provide no benefit (, One technique for turning a checked exception into an unchecked exception is to break the method that throws the exception into two methods, additional method returns a boolean that indicates whether the exception would be thrown, While exception translation is superior to mindless propagation of exceptions from lower layers, it should not be overused, Always document checked exceptions with javadoc, Do not document multiple excetions by their common superclass (, Do not include unchecked exceptions in method, If an exception is thrown by many methods in a class for the same reason, it is acceptable to document the exception in the class’s documentation comment, To capture the failure, the detail message of an exception should contain the values of all parameters and fields that “contributed to the exception”, Exception detail message for programmers, not for users, If an object is immutable, failure atomicity is free, Check parameters for validity before performing the operation, Perform partial computations and then check for validity, Write recovery code to return object to its original state after exception, Make temporary code, apply changes and then replace original object if no exceptions are thrown, Failure atomicity is not always desirable (implementation complexity, performance), If method is not failure atomic, reflect that in documentation, An empty catch block defeats the purpose of exceptions, At the very least, the catch block should contain a comment explaining why it is appropriate to ignore the exception, Synchronization prevent a thread from observing an object in an inconsistent state, Synchronization ensures that each thread entering a synchronized method or block sees the effects of all previous modifications that were guarded by the same lock, Reading or writing a variable is atomic unless the variable is of type, A recommended way to stop one thread from another is to have the first thread poll a, Synchronization has no effect unless both read and write operations are synchronized, Strive to assign mutable data to a single thread, To avoid liveness and safety failures, never give control to the client within a synchronized method or block, Do as little work as possible inside synchronized regions, When in doubt, do not synchronize your class, but document that it is not thread-safe, Executor framework separates unit of work (task) and mechanism (thread creation), Prefer higher-level concurrency utilities (Executor Framework, concurrent collections and synchronizers) to, The presence of the synchronized modifier in a method declaration is an implementation detail, not a part of its exported API, To enable safe concurrent use, a class must clearly document what level of thread safety it supports, To prevent DOS attack, you can use a private lock object instead of using synchronized methods, Best advice for lazy initialization is “don’t do it unless you need to”, If you use lazy initialization to break an initialization circularity, use a synchronized accessor, If you need to use lazy initialization for performance on a static field, use the, If you need to use lazy initialization for performance on an instance field, use the.
