Programming in Java Assignment Help


If you are new to programming in the Java language, have some experience with other languages, and are familiar with things like displaying text or graphics or performing simple calculations, this tutorial could be for you. It walks through how to use the Java® 2 Platform software to create and run three common types of programs written for the Java platform—applications, applets, and servlets. Java is a programming language built for the age of the Internet.  It was built for a world in which everything that has some sort of electronic component: stereo systems, wireless phones, cars, even your refrigerator, are all on the Internet.  This world is right around the corner. What is so unique about Java that has propelled its rapid, wide acceptance?

  • It's available on more devices world-wide than any other language. Notice that I say devices - not just computers. Java is currently being used not only on mainframe systems in the enterprise and personal computers in the office and at home - it's also running in cellphones.
  • It was carefully designed to eliminate many of the most common causes of programming errors - bugs. Java programs that compile error-free tend to work!  Strong data typing and complete memory management are two features that make this possible.
  • It provides for secure programs that can be executed on the Internet without worry of them infecting your system with some virus or planting a trojan horse.

Java was initially modeled after C and C++, minus some potentially confusing features. Pointers, multiple implementation inheritance, and operator overloading are some C/C++ features that are not part of Java. A feature not mandated in C/C++, but essential to Java, is a garbage-collection facility that automatically reclaims objects and arrays. Java's object-oriented focus lets developers work on adapting Java to solve a problem, rather than forcing us to manipulate the problem to meet language constraints. This is different from a structured language like C. For example, whereas Java lets you focus on savings account objects, C requires you to think separately about savings account state (such a balance) and behaviors (such as deposit and withdrawal).

Java's extensive network library makes it easy to cope with Transmission Control Protocol/Internet Protocol (TCP/IP) network protocols like HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol), and simplifies the task of making network connections. Furthermore, Java programs can access objects across a TCP/IP network, via Uniform Resource Locators (URLs), with the same ease as you would have accessing them from the local file system. The Java language is a C-language derivative, so its syntax rules look much like C's. For example, code blocks are modularized into methods and delimited by braces ({ and }), and variables are declared before they are used.

Structurally, the Java language starts with packages. A package is the Java language's namespace mechanism. Within packages are classes, and within classes are methods, variables, constants, and more. When you program for the Java platform, you write source code in .java files and then compile them. The compiler checks your code against the language's syntax rules, then writes out bytecode in .class files. Bytecode is a set of instructions targeted to run on a Java virtual machine (JVM). In adding this level of abstraction, the Java compiler differs from other language compilers, which write out instructions suitable for the CPU chipset the program will run on. At runtime, a Java program indirectly executes on the underlying platform (like Windows or Linux) via a virtual machine (which is a software representation of a hypothetical platform) and the associated execution environment. The virtual machine translates the Java program's bytecodes (instructions and associated data) to platform-specific instructions through interpretation. Interpretation is the act of figuring out what a bytecode instruction means and then choosing equivalent "canned" platform-specific instructions to execute. The virtual machine then executes those platform-specific instructions.

Interpretation makes it easier to debug faulty Java programs because more compile-time information is available at runtime. Interpretation also makes it possible to delay the link step between the pieces of a Java program until runtime, which speeds up development.

The goal of the Java programming language was to make it so that a developer who programmed on one computer could run his/her code on another machine, even if the two machines were nothing alike. With other programming languages, such as C++, the same code is interpreted differently on different machines. Programming on Windows usually meant the program would not work on a Mac. This is not true with Java. Java is a highly portable language as it must be executed through a cross-platform compatible Java Virtual Machine (JVM).Furthermore, Android apps are also developed using Java since the Android Operating System runs on a Java language environment.

Relatively Simple to Use

Java is a high level language, which means Java abstracts away (i.e. handles for you) most of the complex details of the machine (computer) such as memory management, etc. Thus, you can focus on programming instead of worrying about the little details many consider both tedious and difficult.

Less Rewarding from the Start

Java is very stubborn and verbose, which means you need to write a lot of code trying to convince the language to build some feature. Thus, you may need to spend a lot of time coding before you can get a working app. This may be demotivating for coding beginners. Java program development requires a Java software development kit (SDK) that typically includes a compiler, interpreter, documentation generator and other tools used to produce a complete application. Development time may be accelerated through the use of integrated development environments (IDE) - such as JBuilder, Netbeans, Eclipse or JCreator. IDEs facilitate the development of GUIs, which include buttons, text boxes, panels, frames, scrollbars and other objects via drag-and-drop and point-and-click actions. All of the tools you need to start programming in Java are widely available on the Web for free. There is also a huge amount of educational material for Java available on the Web, so once you finish this article you can easily go learn more to advance your skills. You can learn Java programming here without spending any money on compilers, development environments, reading materials, etc. Once you learn Java it is easy to learn other languages, so this is a good place to start.
