What is a Design Pattern

The design pattern is a proven and ready-to-use solution. This is not a class or a library that can be connected to the project, it is something more - it does not depend on the programming language, it is not a complete sample that can be directly converted into code and can be implemented in different ways in different programming languages.

Pros of using templates:

  • reducing the complexity of development due to ready-made abstractions for solving a whole class of problems.
  • facilitating communication between developers by allowing reference to known patterns.
  • unification of solution details: modules and project elements.
  • the opportunity to find a good solution, use it again and again.
  • assistance in choosing the most suitable design option.

Minuses:

  • blindly following some chosen pattern can complicate the program.
  • a desire to try a certain pattern in action without any particular reason.

What are the main characteristics of templates

  • Name - all templates have a unique name that serves to identify them;
  • Purpose - the purpose of this template;
  • Task - a task that the template allows to solve;
  • Solution method - the method proposed in the template for solving the problem in the context where this template was found;
  • Participants - entities taking part in solving the problem;
  • Consequences - the consequences of using a template as a result of actions performed in the template;
  • Implementation is a possible implementation of the pattern.

Methods for reading XML in Java

Image
DOM (Document Object Model) - object - reads XML, recreating it in memory in the form of an object structure, while the XML document is represented as a set of tags - nodes. Each node can have an unlimited number of child nodes. Each child can also contain several levels of descendants or none at all. Thus, the result is a kind of tree. Pluses: Easy to program. If there are many objects in XML with cross-references to each other, it is enough to go through the document twice: first time create objects without references and fill in the name-object dictionary, the second time - restore links. If an error occurs in XML, a half-created XML structure remains in memory, which will be automatically destroyed. Suitable for both reading and writing. Minuses: Low speed. Wastes a lot of memory. SAX (Simple API for XML) - event-driven - reads an XML document, responding to emerging events (opening or closing tag, string, attribute) by calling the event handlers provided by the appl...

XML, well-formed XML and valid XML

Image
XML, the eXtensible Markup Language, is a language with a simple formal syntax, well suited for creating and manipulating documents with programs, and at the same time easy to read and create documents by humans. XML is extensible, it does not fix the markup used in documents, and the developer is free to create markup in accordance with the needs of a particular area, being limited only by the syntax rules of the language. DTD A DTD, Document Type Definition, is a predefined set of rules that defines the relationships between elements and attributes. For example, the DTD for HTML says that the DIV tag must be inside the BODY tag and can appear multiple times, TITLE - in HEAD and only once, and SCRIPT - both there and there as many times as you want. A DTD is usually described directly in the document as a formulation line starting with <!DOCTYPE ... > or in a separate file. Difference between well-formed XML and valid XML Depending on the level of compliance, the document...

ArrayList and LinkedList in Java, memory usage and speed

Image
How much extra memory is needed when calling ArrayList.add()? If there is enough space in the array to accommodate a new element, then no additional memory is required. Otherwise, a new array is created, 1.5 times larger than the existing one (this is true for JDK above 1.7, in earlier versions the size of the increase is different). How much extra memory is allocated when you call LinkedList.add()? One new instance of the nested Node class is created. How much memory to store one byte primitive in LinkedList? Each LinkedList element stores a link to the previous element, the next element, and a data link. private static class Node<E> { E item; Node<E> next; Node<E> prev; //... } For 32-bit systems, each link is 32 bits (4 bytes). The object (header) of the nested Node class itself takes 8 bytes. 4 + 4 + 4 + 8 = 20 bytes, and since the size of each object in Java is a multiple of 8, so we get 24 bytes. A byte primitive occupies 1 by...
