  2. Builder pattern - Wikipedia

    en.wikipedia.org/wiki/Builder_pattern

    Disadvantages of the builder pattern include: [3] A distinct ConcreteBuilder must be created for each type of product. Builder classes must be mutable. May hamper/complicate dependency injection. In many null-safe languages, the builder pattern defers compile-time errors for unset fields to runtime.

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    For example, a simple linearized object would consist of a length field, a code point identifying the class, and a data value. A more complex example would be a command consisting of the length and code point of the command and values consisting of linearized objects representing the command's parameters.

  4. Boilerplate code - Wikipedia

    en.wikipedia.org/wiki/Boilerplate_code

    In Java 14, record classes were added to fight with this issue. [4] [5] [6] To reduce the amount of boilerplate, many frameworks have been developed, e.g. Lombok for Java. [7] The same code as above is auto-generated by Lombok using Java annotations, which is a form of metaprogramming:

  5. Visitor pattern - Wikipedia

    en.wikipedia.org/wiki/Visitor_pattern

    In the case of the CAD example, such format specific behaviors would be implemented by a subclass of Visitor (i.e. SaverPNG). As such, all duplication of type checks and traversal steps is removed. Additionally, the compiler now complains if a shape is omitted since it is now expected by the common base traversal/save function.

  6. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    The designers chose to address this problem with a four-step solution: 1) Introducing a compiler switch that indicates if Java 1.4 or later should be used, 2) Only marking assert as a keyword when compiling as Java 1.4 and later, 3) Defaulting to 1.3 to avoid rendering prior (non 1.4 aware code) invalid and 4) Issue warnings, if the keyword is ...

  7. Async/await - Wikipedia

    en.wikipedia.org/wiki/Async/await

    In the particular case of C#, and in many other languages with this language feature, the async/await pattern is not a core part of the language's runtime, but is instead implemented with lambdas or continuations at compile time. For instance, the C# compiler would likely translate the above code to something like the following before ...

  9. Constructor (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Constructor_(object...

    In Java, a "default constructor" refer to a nullary constructor that is automatically generated by the compiler if no constructors have been defined for the class or in the absence of any programmer-defined constructors (e.g. in Java, the default constructor implicitly calls the superclass's nullary constructor, then executes an empty body ...
