...and lastly to the Internet, one thing has been a constant, different languages evolved based on a need. For these two languages, the Internet was a perfect fit, and without them the Internet would be a less dynamic and vibrant highway. As the Internet grew, more and more people found it a more viable place to do business. With that came a need for languages that were fairly easy to learn, dynamic, secure, portable, and maintainable. The industry answered that call with languages such as Java and JavaScript. This paper will perform an analysis of both Java and JavaScript. In order for the reader to gain a better understanding of these languages, the history of these languages with overviews will be presented along with a discussion of the benefits and drawbacks. The History of Java In the middle of May 1995 Java was introduced into the world, and along with Netscape it would be the new way for Internet users to access this new information superhighway. But before it got to this point, Java technology was developed almost by accident. Back in 1991, Sun Microsystems was looking into the future in anticipation of the future of computing, and they tasked a team that became know as the “Green Project”. Their main focus was to come up with a plan for the future of computing, but what they came out with was something quite unexpected. Under the guidance of James Gosling, a team was locked away in an external site to work on the project that would define Sun’s technology direction...

...we're continuing our Java security research series by analyzing other plug-ins, browser extensions and rich internet applications that are commonly exploited. Our previous research indicated that the current state of Java affairs isn't pretty. At that time, ninety-three percent of enterprises were vulnerable to known Java exploits. Nearly 50 percent of enterprise traffic used a Java version that was more than two years out of date. Through Websense ThreatSeeker Intelligence Cloud analysis we now discover: Only 19 percent of enterprise Windows-based computers ran the latest version of Java (7u25) between August 1-29, 2013. More than 40 percent of enterprise Java requests are from browsers still using outdated Java 6. As a result, more than 80 percent of Java requests are susceptible to two popular new Java exploits: CVE-2013-2473 and CVE-2013-2463. 83.86 percent of enterprise browsers have Java enabled. Nearly 40 percent of users are not running the most up-to-date versions of Flash. In fact, nearly 25 percent of Flash installations are more than six months old, close to 20 percent are outdated by a year and nearly 11 percent are two years old. Our in-depth analysis ran for one month, across multiple verticals and industries. We surveyed millions of real-world web requests for Java usage through our global Websense ThreatSeeker Intelligence Cloud.

...that has made his work popular with programmers for many years. Michael Schidlowsky and Sedgewick have developed concise new Java implementations that both express the methods in a natural and direct manner and also can be used in real applications. Algorithms in Java, Third Edition, Part 5: Graph Algorithms is the second book in Sedgewick's thoroughly revised and rewritten series. The first book, Parts 1-4, addresses fundamental algorithms, data structures, sorting, and searching. A forthcoming third book will focus on strings, geometry, and a range of advanced algorithms. Each book's expanded coverage features new algorithms and implementations, enhanced descriptions and diagrams, and a wealth of new exercises for polishing skills. The natural match between Java classes and abstract data type (ADT) implementations makes the code more broadly useful and relevant for the modern object-oriented programming environment.

...Mohammad Doush Mr. Matthew Robert English 103 13 April 2013 Java the Programming Language Computer is very important in our live, we use computer in everywhere on our live. The doctor uses the computer to see file or pictures of his patients. Also, each engineer uses it in many ways of his work. The teacher in the classroom, employees in the offices and student in their study all of them use computer in them daily live. They are not using the mouse, the keyboard or the scream. They are using the applications by them these applications in the computer are like the soul in the body. The only way to build these applications is programming. To program we need to know one of the programming languages which are very similar each other. If you are professional in one of these languages you can be professional in the other language in a short period of time. It is acceptable if you have the same application written with Java once and with C++ or C sharp at the same time. So for this reason you cannot say that a programming language is better than others. There are three types of programming languages procedural, functional and object-oriented languages. The most uses of these languages are object-oriented and one of these languages is Java you can write any application you need using it. Also you can translate any application to its word. The message of the High-Level programming languages such as Algol and Pascal in first programming revolution was...

...JMaster list of Java interview questions - 115 questions By admin | July 18, 2005 115 questions total, not for the weak. Covers everything from basics to JDBC connectivity, AWT and JSP. 1. What is the difference between procedural and object-oriented programs?- a) In procedural program, programming logic follows certain procedures and the instructions are executed one after another. In OOP program, unit of program is object, which is nothing but combination of data and code. b) In procedural program, data is exposed to the whole program whereas in OOPs program, it is accessible with in the object and which in turn assures the security of the code. 2. What are Encapsulation, Inheritance and Polymorphism?- Encapsulation is the mechanism that binds together code and data it manipulates and keeps both safe from outside interference and misuse. Inheritance is the process by which one object acquires the properties of another object. Polymorphism is the feature that allows one interface to be used for general class actions. 3. What is the difference between Assignment and Initialization?- Assignment can be done as many times as desired whereas initialization can be done only once. 4. What is OOPs?- Object oriented programming organizes a program around its data, i. e. , objects and a set of well defined interfaces to that data. An object-oriented program can be characterized as data controlling 5. access to code. What are Class, Constructor...

...tutorial explains the installation and usage of the Java programming language. It also contains examples for standard programming tasks. 1. Introduction to Java 1.1. History Java is a programming language created by James Gosling from Sun Microsystems in 1991. The first publicly available version of Java (Java 1.0) was released in 1995. Over time new enhanced versions of Java have been released. The current version of Java is Java 1.7 which is also known as Java 7. From the Java programming language the Java platform evolved. The Java platform allows that the program code is written in other languages than the Java programming language and still runs on the Java virtual machine. 1.2. Java Virtual machine The Java virtual machine (JVM) is a software implementation of a computer that executes programs like a real machine. The Java virtual machine is written specifically for a specific operating system, e.g. for Linux a special implementation is required as well as for Windows. Java programs are compiled by the Java compiler into so-called bytecode. The Java virtual machine interprets this bytecode and executes the Java program. 1.3. Java Runtime Environment vs. Java Development Kit Java comes in two flavors, the Java Runtime Environment (JRE) and the Java Development Kit (JDK). The Java runtime environment (JRE) consists of the JVM and the Java class libraries and contains the necessary functionality to start Java programs. The JDK contains in addition the...

...A Comparison between Java and .Net Languages Introduction Java and .Net provide technologies that enable skilled developers to build quality enterprise applications. These technologies are rarely picked based on performance alone. There are many factors to consider when choosing Java or .Net. These considerations are often the deciding factor when choosing one or both of these platforms. Java Java is kenned as both a programming language and a development platform. It was first developed by Sun Microsystems in 1991 and subsequently relinquished in 1995. To help to make the language more accepted and accessible, Sun Microsystems developed it as an object oriented language with a syntax that is very similar to C++. (Java vs. .NET, 2007) Sun Microsystems decided to create this new platform out of a desire to be able to write programs only once that could be run on any system. (James) The Java 2 platform was launched in December 1998. This was a major amelioration of the platform, and included incipient graphics, user interface, and enterprise capabilities. This upgrade was over seven times as large as the initial Java 1.0 release and marked the maturity of the Java platform. (What is java?) Within the Java 2 platform there are 3 editions: • The Java 2 Standard Edition (J2SE) Provides the essential compiler, tools, runtimes, and APIs for writing, deploying, and running applets and applications. • The Java 2 Enterprise Edition (J2EE) Defines a standard for developing multi-tier...

...November 30, 2011 Java Security Jessica Shaw: 628 Robert Grimsley: 596 Java is a programming language developed by Sun Microsystems in 1995, which is now called Oracle. The language itself is derived from the languages C and C++. Java is a simple language compared to C and C++; however they are all object-oriented languages. The language was designed to help minimize the amount of space and take up as little of your computer’s hardware resources as possible. The language was designed upon five key goals, and they are as followed: * It should be "simple, object-oriented and familiar" * It should be "robust and secure" * It should be "architecture-neutral and portable" * It should execute with "high performance" * It should be "interpreted, threaded, and dynamic" Java is used for a multitude of things. Java allows one to play virtual video games, view and design 3D photos, and many other interactive topics on the internet. Java is the main programming language for mobile devices as well as smart phones such as Android by google. Java is a very secure and reliable language that is used by over 800 billion people. Without the Java languages there are millions of applets and interactive applications on websites that wouldn’t preform properly without it. Java is compiled by byte code that allows for the program to be run through the Java Virtual Machine, or JVM. The compiling method allows for...
