...java class loaders http://onjava.com/pub/a/onjava/2005/01/26/classloading.html 1. Bootstrap classes: the runtime classes in rt.jar, internationalization classes in i18n.jar, and others. Whenever a new JVM is started by typing java MyMainClass, the "bootstrap class loader" is responsible for loading key Java classes like java.lang.Object and other runtime code into memory first. The runtime classes are packaged inside of theJRE\lib\rt.jar file. 1. Installed extensions: classes in JAR files in the lib/ext directory of the JRE, and in the system-wide, platform-specific extension directory (such as /usr/jdk/packages/lib/ext on the Solaris™ Operating System, but note that use of this directory applies only to Java™ 6 and later). We can store extension libraries, those that provide features that go beyond the core Java runtime code, in the path given by the java.ext.dirs property. The ExtClassLoader is responsible for loading all .jar files kept in the java.ext.dirs path 1. The class path: classes, including classes in JAR files, on paths specified by the system property java.class.path. If a JAR file on the class path has a manifest with the Class-Path attribute, JAR files specified by the Class-Path attribute will be searched also. By default, the java.class.path property's value is ., the current directory. You can change the value by using the -classpath or -cpcommand-line options, or setting the CLASSPATH environment variable. The command-line options override...

...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...

...CSC 275 Lab 7 Instructor: Angela M. Fults Question Subject Line: CSC 275 Online Lab 7 Question You are to develop an entire program that simulates the way a game is handled in the random creation of its characters. Your program should have the ability to create one of 3 types of character. The choices should be an ogre, archer and a swordsman. Each of these characters will share many of the same types of attributes such as name, life and energy and these should be contained in the Super class that we will call Entity (because Character is already a class). Only the archer and the swordsman are playable, which leaves the ogre to be a Non-Player Character (NPC). This means that the Ogre will be a subclass of the Entity, while the archer and swordsman will be subclasses of Playable which is a subclass of Entity. Below is the diagram. [pic] The Playable class should extend the Entity class and should contain some additional methods that dictate the movement of the character by the user. Note that we will NOT be tracking the movement of the characters to help simplify the lab. The playable class should have a method for moving the character in the 4 standard directions (no diagonals allowed). So up, down, left and right. Class Name: Entity Class Level (global) Variables: strName - String intLife - Integer intEnergy - Integer Method Name: getStrName Parameters: None Desired Result: Accessor Data Returned: strName ...

...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 developed on Windows and it is compatible with other Microsoft technology. The software architecture is not generally limited to one type of language...

...DQ1 WK 1 The article talks mainly about how Microsoft has grown over the years. The .Net Framework is simple, secure, and robust it can accommodate any type of software that is device dependent and would possibly need manipulation of data. People often compare .Net to Java when it comes to programming language. Unfortunately this comparison is not valid, integration is possible without having to rebuild like in Java. The .Net Framework manages memory to prevent overflow and requires the use of verifiable safety so there is less data corruption. With .Net error handling is also much easier. In this article it also states that .Net has a much simpler application build, debugging and deployment platform which would make the program more user friendly. Programmers are able to view the application while they are building it. .Net is versatile and makes programming a lot faster. DQ2 WK1 In the article a difference was in the refactoring section, it states that with XP the programmers revise their product designs and the underlying architecture on a continuous basis which would allow accommodations to new functionalities and also put a stop to redundancy in coding. With Microsoft, well everything is pretty much based off observations and interactions with the product. By creating daily builds, the Microsoft types believe this is how they are able to show progress before releasing the Beta version. In another section, “Simple Design” states that with XP teams the process is “ Build...

...Utilizing the Internet and various sources, research the .NET Framework to answer the following questions: • When was the .NET framework created? • What is the common language runtime (CLR)? • What is the difference between .NET and ASP.NET, if any? • What languages currently comprise the .NET language? o Compare and contrast each language against the other. The .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2000 the first beta versions of .NET 1.0 were released. The Common Language Runtime (CLR) is the virtual machine component of Microsoft's .NET framework and is responsible for managing the execution of .NET programs. .NET is an object-oriented language. You use namespaces to get specific classes you need to use to do your work, and you use subroutines and functions to determine how the server processes user input. ASP.NET is an object-oriented, event-driven programming model for Web pages. Like all .NET programs, you can write ASP.NET pages in any of the four supported languages. 1.APL - is an interactive array-oriented language and integrated development environment, which is available from a number of commercial and noncommercial vendors and for most computer platforms. It is based on a mathematical notation developed by Kenneth E. Iverson and associates that features special attributes for the design and specifications of digital computing systems, both computer hardware and software. ...

...Reusability of Code One of the key factors for large software development projects is the ability to reuse code amongst team members. This allows for efficiency and reduces the time to get a software product delivered to a customer (or brought to market). This paper is intended to focus on the different areas that would benefit a software development team (or company) by having a structured and reusable code library in place. I have experience in supporting large ECM (Electronic Content Management) systems and I will refer to these re-world scenarios throughout this document. Reusability refers to the ability for a single developer that specializes in one area (or is assigned the task of developing) to develop a class or specific code that can then be used by other developers. As an example, a senior developer defines a class that serves as a blueprint for developing various objects that would input data into a Filenet ECM system. Once this class has been defined and created, other developers can reuse this class to develop objects that allow for public input and that will eventually store data in the ECM database. This stored data that is specifically formatted to be read by the Filenet application, allows end users to run reports that have a specific output that the want to view. In essence, the reusability of code is akin to manufacturing one part of a car that can then be used for many cars (such as a single frame that can hold various models of cars). The developer...

...advantage is that with the use of the Java Virtual Machine, code can be written once and run on almost any system without having to recode it. Students must take these differences into account when deciding which platform to choose. Introduction Object-oriented programming helps to make computer programs much more manageable through the use of reusable objects, inheritance and polymorphism. It was first developed by Dr. Alan Kay and a group of programmers at Xerox in the 1970’s. They developed a language called Smalltalk which was the first to really flesh out object-oriented ideas.(Murphy, 2008) The first wide commercial use of object orientation began with the invention of the C++ language in the early 1980’s; when Bjarn Stroustrup integrated object oriented concepts into the already established C language.(Dolya, 2003) Since then, the Java platform and the .NET platform, and their associated languages, have become the two main players in software development. According to Payton Byrd (2010), "The future of software development is now expected to be a near 50-50 split between Java and .NET. When making a decision on which technology to bank on, you...

...Encapsulation is whereby variables, functions are protected from being accessed by other codes outside the class. This helps manage the code being protected and has least if any impact on other parts of a program if change was to occur in the protected code. Encapsulation is important in java due to its flexibility and it is easy to change with new requirement, the class has total control over what is stored in its field, one part of the code can be changed and the rest of the would not be affected and also encapsulation is useful since it is easy to maintain. Both the mutator and accessor method are used to enforce data encapsulation where their jobs is returning and setting the value state of an object. Mutator method is used to set the private field value. It is denoted by using set at the beginning of the method name. Example of a mutator method would be public void setSchool (String school). Accessor method is used to return the private field value. It is denoted by using get at the beginning of the method name. An example of accessor method would be public String getFirstName () Implicit parameter is the object on which the method is invoked whereas explicit parameter is the parameter of the method other than the object the method is invoking and is enclosed in a parentheses. To access an explicit parameter variable inside the method refer the parameter variable by its name. To illustrate what is an implicit and explicit parameter we use the following code: Person...
