The first version of the Java programming language is released.

Java is a high-level, general-purpose programming language that was developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It is known for its simplicity, portability, and robustness. Java is widely used for developing a wide range of applications, from desktop software to mobile apps and large-scale enterprise systems.

Here are some key features and aspects of the Java programming language:

Object-Oriented: Java is an object-oriented programming (OOP) language, which means it emphasizes the concept of objects that encapsulate data and behavior. It supports the principles of inheritance, encapsulation, polymorphism, and abstraction.

Platform Independence: One of the main advantages of Java is its platform independence. Java source code is compiled into bytecode, which can run on any platform with a Java Virtual Machine (JVM). This “write once, run anywhere” principle allows Java programs to be executed on different operating systems without requiring any modifications.

Automatic Memory Management: Java implements automatic memory management through a technique called garbage collection. It frees developers from explicitly allocating and deallocating memory, as the JVM automatically handles memory allocation and reclaims unused memory.

Rich Standard Library: Java provides a comprehensive standard library that offers a wide range of classes and methods for common programming tasks. It includes utilities for string handling, networking, input/output (I/O), collections, GUI (Graphical User Interface), and much more.

Multi-threading: Java has built-in support for multi-threading, allowing developers to create and manage multiple threads of execution within a single program. This enables concurrent programming, where different parts of a program can run independently and simultaneously.

Strong Community and Ecosystem: Java has a vast and active community of developers who contribute to its ecosystem by creating libraries, frameworks, and tools. This ecosystem provides a wealth of resources, documentation, and support for Java developers.

Security: Java has built-in security features that help create secure applications. The Java Security Manager allows fine-grained control over access to system resources, and the sandbox environment restricts the execution of potentially harmful code.

Widely Used: Java is widely used in various domains, including enterprise software development, web development, Android app development, scientific applications, financial systems, and more. Many popular frameworks and platforms, such as Spring, Hibernate, and Apache Hadoop, are built using Java.

Continuous Evolution: Java is a language that has continued to evolve over time. It follows a release cycle, with regular updates introducing new features and enhancements. The Java community actively contributes to the evolution of the language through the Java Community Process (JCP).

The New York Public Library is opened.

The Stephen A. Schwarzman Building, commonly known as the Main Branch or the New York Public Library, is the flagship building in the New York Public Library system and a landmark in Midtown Manhattan, New York City. The branch, one of four research libraries in the library system, contains nine separate divisions. The structure contains four stories open to the public. The main entrance steps are at Fifth Avenue at its intersection with East 41st Street. As of 2015, the branch contains an estimated 2.5 million volumes in its stacks.

The Main Branch was built after the New York Public Library was formed as a combination of two libraries in the late 1890s. The site, along Fifth Avenue between 40th and 42nd Streets, is located directly east of Bryant Park, on the site of the Croton Reservoir. The architectural firm Carr√®re and Hastings constructed the structure in the Beaux-Arts style, and the structure opened on May 23, 1911. The marble facade of the building contains ornate detailing, and the Fifth Avenue entrance is flanked by a pair of stone lions that serve as the library’s icon. The interior of the building contains the Main Reading Room, a space measuring 78 by 297 feet with a 52-foot-high ceiling; a Public Catalog Room; and various reading rooms, offices, and art exhibitions.

The Main Branch was originally called the Central Building and was later known as the Humanities and Social Science Center. The Main Branch became popular after its opening, and saw 4 million annual visitors by the 1920s. It formerly contained a circulating library, though the circulating division of the Main Branch moved to the nearby Mid-Manhattan Library in the 1970s. Additional space for the library’s stacks constructed under adjacent Bryant Park was added in 1991, and the branch’s Main Reading Room was restored in 1998. A major restoration from 2007 to 2011 was underwritten by a $100 million gift from philanthropist Stephen A. Schwarzman, for whom the branch was subsequently renamed. Since 2018, the branch has been undergoing an additional expansion that is expected to be completed in 2021.

The building was declared a National Historic Landmark in 1965, and listed on the National Register of Historic Places the following year. It was made a New York City designated landmark in 1967, though parts of the interior were separately listed as New York City designated landmarks in 1974 and 2017.

The Main Branch has been featured in many television shows, including Seinfeld and Sex and the City, as well as films such as The Wiz in 1978, Ghostbusters in 1984, and The Day After Tomorrow in 2004.

The Alaskan volcano, Mount Cleveland erupts.

Eruptions from Mount Cleveland are generally vulcanian and strombolian in nature, characterized by short explosive ash clouds sometimes accompanied by a’a flows, lava fountains, pyroclastic flows, ash and steam emissions, lava dome growth, and the ejection of breadcrust bombs. Hot springs were reportedly found on the volcano in the 1800s, and persistent fumarolic activity was observed in the 1980s and 1990s. Mount Cleveland is a site of persistent steam emissions and thermal anomalies that represent constant background activity. During 2011, a summit lava dome formed, by continuous intrusion of magma at the summit. Late in 2011, nearly 6 explosions demolished the dome. In June 2012, another small dome was observed.

Little is known about Cleveland’s early eruptive history as its remoteness makes it a difficult area to investigate, and discrepancies in names have caused confusion between events there and those on nearby Carlisle. Even today, not all possible events are confirmed as eruptions by the Alaska Volcano Observatory, and many are listed as “possible.” In observed history, Mount Cleveland may have first erupted in 1744; the first confirmed eruption occurred in 1828. The volcano erupted again in 1836, 1893, 1897, 1929, 1932, and 1938.

The first notable eruption from Mount Cleveland was a Volcanic Explosivity Index 3 Vulcanian eruption that occurred between June 10 and June 13, 1944. Lava flows extended 5 km from the summit, and an ash plume 6,000 m high was produced. Large boulders were reportedly ejected and carried out to sea by eruptive force. The eruption had the distinction of being the only confirmed direct volcanic fatality in Alaska; a small detachment from the Eleventh Air Force was stationed on the volcano at the time, and one Sergeant Purchase left his post early in the eruption to take a walk and never returned, probably killed by mudslides. At approximately 10:20, a boat sent to search for Purchase witnessed the end of the eruption. The island was abandoned for the remainder of the war.

Mount Cleveland erupted more recently in 1951, 1953, 1954, 1975, 1984 through 1987, 1989, 1994, and 1997. The volcano has received more focused attention in recent times due to its increased activity: it erupted in 2001, 2005, three times in 2006, 2007, three times in 2009, and twice in 2010. Of these, the most significant eruption was the 2001 eruption, which produced a 12 km high ash plume. This plume dispersed 120 to 150 km 75 to 93 mi across Alaska, an unusual distance that allowed detailed satellite observations to be made. Nikolski and the surrounding region was the site of several hours of ashfall, represented in satellite imagery as areas of discolored snow.This eruption significantly disrupted air traffic in the area.

On June 19, 2012, a pilot reported an ash-producing explosion on Mount Cleveland. Due to continuing seismic activity, the volcano was placed on the USGS Volcano Watch List in the orange or “watch” category the following day. AVO continues to keep Cleveland on the watch because of a persistent anomaly at the summit. AVO suspects it could be dome growth. Other minor ash producing explosions occurred on June 26, July 12, and August 19.

The first version of the Java programming language is released.

On 23 May 1995, John Gage, the director of the Science Office of the Sun Microsystems along with Marc Andreesen, co-founder and executive vice president at Netscape announced to an audience of SunWorldTM that Java technology wasn’t a myth and that it was going to be incorporated into Netscape Navigator.

At the time the total number of people working on Java was less than 30. This team would shape the future in the next decade and no one had any idea as to what was in store. From running an unmanned vehicle on Mars to serving as the operating environment of most consumer electronics, e.g. cable set-top boxes, VCRs, toasters and PDAs, Java has come a long way from its inception. Let’s see how it all began.

In December of 1990, a project was initiated behind closed doors with the aim to create a programming tool that could render obsolete the C and C++ programming languages. Engineer Patrick Naughton had become extremely frustrated with the state of Sun’s C++ and C APIs (Application Programming Interfaces) and tools. While he was considering to move towards NeXT, he was offered a chance to work on new technology and the Stealth Project was started, a secret nobody but he knew.

This Stealth Project was later named the Green Project when James Gosling and Mike Sheridan joined Patrick. As the Green Project teethed, the prospects of the project started becoming clearer to the engineers working on it. No longer did it aim to create a new language far superior to the present ones, but it aimed to target devices other than the computer.

Staffed at 13 people, they began work in a small office on Sand Hill Road in Menlo Park, California. This team came to be called the Green Team henceforth in time. The project they underwent was chartered by Sun Microsystems to anticipate and plan for the “next wave” in computing. For the team, this meant at least one significant trend, that of the convergence of digitally controlled consumer devices and computers.
