...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. The Web site for this book (www.cs.princeton.edu/~rs/) provides additional source code for programmers along with a variety of academic support materials for educators. Coverage includes: A complete overview of graph properties and types Diagraphs and DAGs Minimum spanning trees Shortest paths Network flows Diagrams, sample Java code, and detailed algorithm descriptions A landmark revision, Algorithms in Java, Third Edition, Part 5 provides a complete tool set for programmers to implement, debug, and use graph algorithms...

...Programming--Malone Basics of Java Programming (A Work In Progress) What Constitutes a Java Program? A Java program consists of one or more source files. Each source file is called .java, where is the name of the class contained in that source file and .java is the extension that identifies the file as a Java source code file. In general, each source file contains one class. The name of the class must match the name of the file (without the extension) exactly. To execute a Java program, you first need to compile the source code into byte code. Byte code files have the name .class. If you’re working from the shell, this is done using the javac command (where “c” is for compiler). Usually we will be compiling using the Xcode IDE. Once compiled, the program is executed using the Java interpreter (a.k.a. the Java Virtual Machine or JVM). From the shell, the JVM is invoked with the “java” command. Again we will usually be doing this with the Build and Go or Debug options of the Xcode IDE. A Java program must have a routine called main(), which is the starting point for program execution. main() will always look something like this: public static void main (String args[]) { // insert code here... System.out.println("Hello World!"); } Source Code Formatting Keep in mind the following when writing Java source code: Java is case sensitive (“foo”, “Foo”, and “fOO” are all considered to be different in Java). • Every line of code in Java must end in a semi-colon (“;”). • Java doesn’t care about white...

...Advantages and Disadvantages of Java v. .NET University of Phoenix CSS/422 .NET and Java There is no shortage of definitions for software architecture but in a general sense it is the blueprint for a system, its properties and the relationships among all of the elements. It specifies all of the actions to be taken by the design and implementations teams. There are various differences between .NET and Java Technology so there are certainly advantages and disadvantages to using one or the other as software architecture. The choice, however, depends on the scope of the project and the skill of the design team. Both .NET and Java have platforms that offer a good solid foundation for project design. Java Technology is the choice of many developers because of its work-saving features and ease of use. “.NET and web services are tightly integrated and it is easier to create a basic web service in .NET” (Ranck, 2002). Advantages A major advantage of .NET is that it allows for the use of multiple languages and horizontal scalability. This feature makes it an ideal choice by developers for software architecture if they want to write programs in C++, Java or Virtual Basic because it provides a unified environment in which to work. It is easily developed and supported. Unfortunately, the same cannot be said for Java which is limited to use with the Java programming language only. Another advantage of .NET is that the interface is easily...

...also used for hardware design. The idea of creating a new language originated from Stroustrup's experience in programming for his Ph.D. thesis. Stroustrup found that Simula had features that were very helpful for large software development, but the language was too slow for practical use, while BCPL was fast but too low-level to be suitable for large software development. 1990’s Java was created by James Gosling at Sun Microsystems. Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. James Gosling aimed to implement a virtual machine and a language that had a familiar C/C++ style of notation. JavaScript is not related to Java. It was originally developed in Netscape, by Brendan Eich. Battling with Microsoft over the Internet, Netscape considered their client- server solution as a distributed OS, running a portable version of Sun Microsystems' Java. Because Java was a competitor of C++ and aimed at professional programmers, Netscape also wanted a lightweight interpreted language that would complement Java by appealing to nonprofessional...

...Java Class MIS 304 is not a class for everyone. Not just any student should take the class. This class is structured to assist students in learning how to program using the Java language. This class does not make a student an expert in the language of Java, but instead gives the student the basic fundamentals needed to have practical use of the language and gives them a solid foundation upon which they can build if they choose to do so. The material covered in the class is adequate. Java can be a complex language to learn, but in MIS 304 one is taught the basics and nothing too detailed or complicated. The resources that are given to the students are very good. I know that the Java book used for the class is one of the best reference materials on Java that is on the market today. The lab facilities and proctors are also great resources. The only problem I feel that exists is that students don’t take advantage of the resources they have available. Students hardly look through their book for answering questions they might have. Also students hardly even bring their books to the lab when doing programs. They sometimes look for proctors to fix their problems instead of fixing it themselves. I think it should be emphasized to students that the proctors are not their to do the programs for them, but to rather help them figure out what is going wrong in their programs. Also it should be emphasized that the book should be with them when working on programs so that if questions or...

...millions of dollars. Many of these lawsuits are held in Eastern Texas because of the favorable outcome likely to the patent holder. On top of the cost to the successful developer there is also the public reputation loss to take into account. Would you buy a product if you believed that that product was stolen intellectual property? Thus in one blow large companies take aim as much for the other companies reputation with bad press as it does for money. Sometimes the company holding the patent did not even develop the product that he patent is covering. One such battle is currently being fought. Oracle is suing Google for patent violations that they acquired by purchasing Sun. Prior to this recent purchase Oracle had very little to do with Java, the programming language that the patent violation are for. While this is not what is commonly known as patent trolling, where a small company sues a large company primarily for revenue using a frivolous patent, it is what I believe to be patent pirating. Open source is a coding standard that allows all users to look at source code and learn from it, copy and modify it, and distribute it freely with certain restrictions. This...

...1970’s: Smalltalk is an object-oriented, dynamically typed, reflective programming language. Smalltalk was created as the language to underpin the "new world" of computing exemplified by "human–computer symbiosis."[1] It was designed and created in part for educational use, more so for constructionist learning, at the Learning Research Group (LRG) of Xerox PARC by Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Scott Wallace, and others during the 1970s. The language was first generally released as Smalltalk-80. Smalltalk-like languages are in continuing active development, and have gathered loyal communities of users around them. ANSI Smalltalk was ratified in 1998 and represents the standard version of Smalltalk. Compiler Description Language, or CDL, is a programming language based on affix grammars. It was designed for the development of compilers. It is very limited in its capabilities and control flow; and intentionally so. The benefits of these limitations are twofold. On the one hand they make possible the sophisticated data and control flow analysis used by the CDL2 optimizers resulting in extremely efficient code. The other benefit is that they foster a highly verbose naming convention. This in turn leads to programs that are to a great extent self-documenting. The original version, designed by Cornelis H. A. Koster at the University of Nijmegen emerged in 1971. Pascal is a historically influential imperative and procedural programming language, designed in...

...Middleware for Distributed Systems Evolving the Common Structure for Network-centric Applications Richard E. Schantz BBN Technologies 10 Moulton Street Cambridge, MA 02138, USA schantz@bbn.com Douglas C. Schmidt Electrical & Computer Engineering Dept. University of California, Irvine Irvine, CA 92697-2625, USA schmidt@uci.edu 1 Overview of Trends, Challenges, and Opportunities Two fundamental trends influence the way we conceive and construct new computing and information systems. The first is that information technology of all forms is becoming highly commoditized i.e., hardware and software artifacts are getting faster, cheaper, and better at a relatively predictable rate. The second is the growing acceptance of a network-centric paradigm, where distributed applications with a range of quality of service (QoS) needs are constructed by integrating separate components connected by various forms of communication services. The nature of this interconnection can range from 1. The very small and tightly coupled, such as avionics mission computing systems to 2. The very large and loosely coupled, such as global telecommunications systems. The interplay of these two trends has yielded new architectural concepts and services embodying layers of middleware. These layers are interposed between applications and commonly available hardware and software infrastructure to make it feasible, easier, and more cost effective to develop and evolve systems using reusable software.

...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...
