LAN (Local Area Network) - permalink - collapse

All > Technology > Programming > Java

A Local Area Network (LAN) is a group of devices connected with various communications technologies in a small geographic area. Ethernet is the most widely-used LAN technology. Communication on a LAN can either be with Peer-to-Peer devices or Client-Server devices.

LCDUI (Liquid Crystal Display User Interface) - permalink - collapse

All > Technology > Programming > Java

LCDUI is a shorthand way of referring to the MIDP user interface APIs, contained in the javax.microedition.lcdui package. Strictly speaking, LCDUI stands for Liquid Crystal Display User Interface. It's a user interface toolkit for small device screens which are commonly LCD screens.

left shift operator - permalink - collapse

All > Technology > Programming > Java

The left shift operator (<<) is a bit manipulation operator. It moves the bits in its left operand zero or more places to the left, according to the value of its right operand. Zero bits are added to the right of the result.

lexicographic ordering - permalink - collapse

All > Technology > Programming > Java

The ordering of words as they would be found in a dictionary. It should be noted that different locales order similar looking words according to their own conventions - this applies, in particular, to accented characters.

life cycle (J2EE component) - permalink - collapse

All > Technology > Programming > Java

The framework events of a J2EE component's existence. Each type of component has defining events that mark its transition into states in which it has varying availability for use. For example, a servlet is created and has its init method called by its container before invocation of its service method by clients or other servlets that require its functionality. After the call of its init method, it has the data and readiness for its intended use. The servlet's destroy method is called by its container before the ending of its existence so that processing associated with winding up can be done and resources can be released. The init and destroy methods in this example are callback methods. Similar considerations apply to the life cycle of all J2EE component types: enterprise beans, Web components (servlets or JSP pages), applets, and application clients.

LIFO (last in, first out) - permalink - collapse

All > Technology > Programming > Java

The (LIFO) semantics of a stack data structure. Items are removed in the opposite order to which they arrived in the stack, so newer items are always removed before older ones. See first in, first out.

little-endian - permalink - collapse

All > Technology > Programming > Java

A common difference between machines is the order in which they store the individual bytes of multi-byte numerical data. A little-endian machine stores the lower-order bytes before the higher-order bytes. See big-endian.

livelock - permalink - collapse

All > Technology > Programming > Java

A situation in which a thread waits to be notified of a condition but, on waking, finds that another thread has inverted the condition again. The first thread is forced to wait again. When this happens indefinitely, the thread is in livelock.

locale - permalink - collapse

All > Technology > Programming > Java

Details which are dependent upon conventions and customs adopted by a particular country or culture. Within programs, this affects issues such as number and date formatting, for instance. Designers of classes should be sensitive to the locale-specific issues that might apply to users.
