...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......

...Read Me First Introduction JAVA™ IS A FULL-FEATURED, GENERAL-PURPOSE PROGRAMMING LANGUAGE WITH MANY CAPABILITIES. IT CAN SERVE AS A STANDALONE LANGUAGE FOR A VARIETY OF APPLICATIONS, INCLUDING DESKTOP AND SOME MOBILE PROGRAMS. THIS COURSE CLOSELY ALIGNS WITH THE ORACLE CERTIFIED ASSOCIATE JAVA™ SE EXAMINATION. Course Overview Week One includes an overview of how programming languages work and an introduction to Java™ and the Java™ Virtual Machine (JVM). The JVM is what enables the same Java™ program to run unchanged on multiple platforms. You learn Java™ syntax by writing a program that compiles and executes. You begin with the simplest programs that display a message to the user; however, the structure that you use carries forward into more complex programs later on. Week Two focuses on two of the most important concepts in programming: selection and repetition. Selection allows you to make a choice between alternatives and determine which block of statements will be executed as a result. Repetition allows the program to repeat a block of code multiple times. This enables you to write programs that can do a lot of processing with very few lines of code. For example, you may want to read all of the records in a data file. With a repetition structure, you can write this in just a few lines. If repetition structures were not available, you would have to write a line of code for every record in the file. In Week Three, you will look at methods and constructors......

...Visual Basic has been labeled to be the most successful programming language in the history of programming. In 1991, Microsoft built Visual Basic on the older BASIC language – Beginner’s All purpose Symbolic Instruction Code (Mabutt). In the late 1980s, Alan Cooper, owner of Tripod, developed drag-and-drop interface, Ruby, which was also an influence to the idea of Visual Basic (History of Visual Basics). Just like any spoken language, rules must be followed in order to create effective communication between two people. For programming languages, it is necessary to follow all naming rules in order to build the program. Visual Basic’s variable name rules are as follows: Up to 255 characters, names must begin with a letter, no embedded spaces or special characters are to be used besides the underscore “__”, there cannot be a reserved word, uppercase and lowercase should be used with a purpose, and names cannot be repeated with the same level of scope (Visual Basic Naming Rules). If a developer does not follow these rules when using Visual Basic, there will be errors that may occur even before the program can be tested. Python Python is another common programming language, and was influenced by the design of ABC (Lukaszewski). In the 1996, Guido van Rossum created his very own version of ABCs, which we all know now as Python (Lukaszewski). Python is a basic syntax used for statement grouping, a list, strings, and numbers (Lukaszewski). Because it is another programming......

...class file in Java 1. class file in java is generated when you compile .java file using any Java compiler like Sun's javac which comes along JDK installation and can be found in JAVA_HOME/bin directory. 2. class file contains byte codes. byte codes are special platform independent instruction for Java virtual machine. bytecode is not a machine language and mere instruction to JVM. since every machine or processor e.g. INTEL or AMD processor may have different instruction for doing same thing, its left on JVM to translate bytecode into machine instruction and by this way java achieves platform independence. 3. class file of inner class contains $ in there name. So if a Java source file contains two classes, one of them is inner class than java compiler will generate two class file. separate class file for top level and inner class. you can distinguish them by looking at there name. Suppose you have top level class as "Hello" and inner class as "GoodBye" then java compiler will generate two class file: Hello.class Hello$GoodBye.class Hello$GoodBye.class is a class file for inner class. whose name is in format of top-class$inner-class. 4. You can look bytecode of class file using javap command. javap command can also display method and field information from .class file. see my post how to decompile .class file in Java for more details. 5. class file format is subject to change and its changed to support new feature introduced in Java 1.5. In general every java compiler......

...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......

...1970’s CLU is a programming language created at MIT by Barbara Liskov and her students between 1974 and 1975. It was notable for its use of constructors for abstract data types that included the code that operated on them, a key step in the direction of object-oriented programming (OOP). Euclid is an imperative programming language for writing verifiable programs. It was designed by Butler Lampson and associates at the Xerox PARC lab in the mid-1970s. The implementation was led by Ric Holt at the University of Toronto and James Cordy was the principal programmer for the first implementation of the compiler. It was originally designed for the Motorola 6809 microprocessor. Forth is an imperative stack-based computer programming language and programming environment. Language features include structured programming, reflection (the ability to modify the program structure during program execution), concatenative programming (functions are composed with juxtaposition) and extensibility (the programmer can create new commands). Although not an acronym, the language's name is sometimes spelled with all capital letters as FORTH, following the customary usage during its earlier years. Forth was designed by Charles H. Moore and appeared in the 1970’s. GRASS is the original version of GRASS was developed by Tom DeFanti for his 1974 Ohio State University Ph.D. thesis. It was developed on a PDP-11/45 driving a Vector General 3DR display, and as the name implies, this was a purely......

...naming rules for Visual Basic, Python, and Java have many different facets to them. These are the most common and most used programming languages in use today. Over the years these languages have become more user-friendly and easier to comprehend to write programs. Visual Basic is most used in introductory program writing and common for students’ first learning of programming. Some of the naming rules for Visual Basic are: the first character of the name must be a letter, you can’t use a space, period, exclamation point, or these special characters - &, @, $, or # in the name, the name cant’ exceed 255 characters in length, and Visual Basic isn't case-sensitive, but it preserves the capitalization in the statement where the name is declared. (Microsoft, 2014) Python provides a special process called the PEP process, short for Python Enhancement Process for changes proposed to Python. (University, 2014) Some of the naming rules for Python are as follows : indentation should be done using four spaces per indentation level, lines should be less than 80 characters as compared to Visual Basic and its use of a maximum of 255 characters, and lines that get too long should be aligned in a “reasonable” fashion, for example aligned with an open delimiter and at a different indentation level than any following indented suites. These are just some of the parameters to consider when naming in Python as there are many other rules to consider. Java is probably......

...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......
