Logical and bitwise operations and operators in Java

Logical operations and operators

  • & : Logical AND;
  • && : Shorthand AND;
  • | : Logical OR;
  • || : Shorthand OR;
  • ^ : Logical XOR (exclusive OR);
  • ! : Logical unary NOT;
  • &= : AND with assignment;
  • |= : OR with assignment;
  • ^= : XOR with assignment;
  • == : Equal;
  • != : Not equal;
  • ?: : Ternary conditional operator.

What is the ternary selection operator

Ternary conditional operator ?: is an operator that can replace some constructions of if-then-else statements.

The expression is written in the following form: 

condition ? expression1 : expression2

If the condition is met, then expression1 is evaluated and its result becomes the result of the entire statement. If the condition is false, then expression2 is evaluated and its value becomes the result of the operator's operation. Both expression1 and expression2 must return the same (or compatible) type.

Bitwise operations

  • ~ : Bitwise unary NOT operator;
  • & : Bitwise AND;
  • &= : Bitwise AND assignment;
  • | : Bitwise OR;
  • |= : Bitwise OR with assignment;
  • ^ : Bitwise exclusive XOR;
  • ^= : Bitwise exclusive XOR with assignment;
  • >> : Shift to the right (division by 2 in the degree of shift);
  • >>= : Shift right with assignment;
  • >>> : Shift to the right without taking into account the sign;
  • >>>= : Shift to the right ignore the sign with assignment;
  • << : Shift left (multiply by 2 in the degree of shift);
  • <<= : Left shift with assignment.

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...
