Interface (Java)

An interface in Java programming language is an abstract type that is used to specify an interface (in the generic sense of the term) that classes must implement. Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final). All methods of an Interface do not contain implementation (method bodies) as of all versions below Java 8. Starting with Java 8, default and static methods may have implementation in the interface definition.

Interfaces cannot be instantiated, but rather are implemented. A class that implements an interface must implement all of the methods described in the interface, or be an abstract class. Object references in Java may be specified to be of an interface type; in each case, they must either be null, or be bound to an object that implements the interface.

One benefit of using interfaces is that they simulate multiple inheritance. All classes in Java must have exactly one base class, the only exception being java.lang.Object (the root class of the Java type system); multiple inheritance of classes is not allowed.

Interface (novel)

Interface is a 1994 novel by Neal Stephenson and George Jewsbury. It was originally sold with the author pseudonym of Stephen Bury, then reissued as being by Bury and J. Frederick George, and most recently as being by Stephenson and George.

Interface is a near-future thriller, set in 1996, in which a shadowy coalition bent on controlling the world economy attempts to manipulate a candidate for president of the United States through the use of a computer bio-chip implanted in his brain.

In 2007, it was described by writer Cory Doctorow as an "underappreciated masterpiece".

Plot summary

The novel opens with the governor of Illinois, William Cozzano, suffering a stroke, and in a separate subplot, a trailer park inhabitant, unemployed African-American, Eleanor Richmond, discovering her husband dead after having committed suicide in their repossessed former home.

As events progress, an underground business coalition, the Network, is arranging for Cozzano to have a biochip implanted and for him to run for President of the United States. The Network is made up of a number of large fictional companies, with parallels in real business entities.

Interface (album)

Interface is the debut album by Dominion. It was released in 1996 on Peaceville Records.

Interface (computing)

In computing, an interface is a shared boundary across which two separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans and combinations of these. Some computer hardware devices such as a touchscreen can both send and receive data through the interface, while others such as a mouse, microphone or joystick are one way only.

Hardware interfaces

Hardware interfaces exist in many of the components such as the various buses, storage devices, other I/O devices, etc. A hardware interface is described by the mechanical, electrical and logical signals at the interface and the protocol for sequencing them (sometimes called signaling). A standard interface, such as SCSI, decouples the design and introduction of computing hardware, such as I/O devices, from the design and introduction of other components of a computing system, thereby allowing users and manufacturers great flexibility in the implementation of computing systems. Hardware interfaces can be parallel with several electrical connections carrying parts of the data simultaneously, or serial where data is sent one bit at a time.

Java

Java (Indonesian: Jawa; Javanese: ꦗꦮ) is an island of Indonesia. With a population of over 141 million (the island itself) or 145 million (the administrative region) as of 2015 Census released in December 2015, Java is home to 56.7 percent of the Indonesian population, and is the most populous island on Earth. The Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.

Formed mostly as the result of volcanic eruptions, Java is the 13th largest island in the world and the fifth largest in Indonesia. A chain of volcanic mountains forms an east–west spine along the island. Three main languages are spoken on the island, with Javanese being the dominant; it is the native language of about 60 million people in Indonesia, most of whom live on Java. Most residents are bilingual, with Indonesian as their first or second language. While the majority of the people of Java are Muslim, Java has a diverse mixture of religious beliefs, ethnicities, and cultures.

Java (programming language)

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

Java chicken

The Java is a breed of chicken originating in the United States. Despite the breed's name, which comes from the island of Java, it was developed in the U.S. from chickens of unknown Asian extraction. It is one of the oldest American chickens, forming the basis for many other breeds, but is critically endangered today. Javas are large birds with a sturdy appearance. They are hardy, and are well-suited for both meat and egg production, especially by small-scale farms, homesteads, and backyard keepers.

History

After the Dominique, the Java is the oldest breed of chicken created in the U.S. Though its name would suggest a Javan derivation, it is not known exactly where in Asia its ancestors came from. It was first mentioned in print in 1835, but it is thought to have been present well before this time. Javas were especially notable as meat production birds throughout the 19th century, with their popularity peaking in the latter half of that century.

The Java is a key foundation breed for the American class of chickens, having contributed significantly to major modern fowl such as the Jersey Giant, Rhode Island Red and Plymouth Rock. They are also likely to be the source of the yellow skin in contemporary Dominiques, which once had white skin.
