Java vs. Java Script

Java and Java Script share two very similar names, but they are completely

different languages that possess few commonalties. They differ both in their purpose and

the applications they can run. Java Script does not permit programmers to create stand

alone applications, or applications that can run by themselves that are not imbedded in

another language, while Java is a complex language that allows programmers to create

entire stand alone applications, or applications that run all buy themselves. Java Script is

a much simpler language, similar in structure to HTML, and thus, Java Script is much

easier to learn, but it must always be imbedded in another text, usually HTML.

One similarity of the two languages is that they are both object -oriented

languages. Object oriented languages allow programmers to change properties of objects.

Thus, the actions you can take depend on the type of object you are manipulating. For

example, if you are working with shapes like squares and circles, and the action you wish

to take is to make the objects 3D, the squares will become cubes while circles spheres.

Discussion on the topic based upon my research:

Java

Some have asked what is Java, exactly? Java is a programming language designed

to allow programmers to create applications that can be downloaded from a network and

run safely on almost any computing platform.

It runs on almost all types of computers,

supplies software components as needed, and contains built-in security features. The

language was designed similar to C++, but with syntax that is easier to understand. While

it incorporates all the recent major advances in computer sciences, it is still so young it

lacks the tools available for programming that are available in C++ or visual basic.

Java is considered by some the closest thing that we have to a universal computer

language. Java’s virtual machine, made up of software, allows Java to run on almost any

computer. The virtual machine does is takes messages from the computer and translates

them for Java, and vice versa. Because Java’s virtual machine is so unique and powerful,

it has been compared to the structure of Esperanto.

Incipient stages of Java emerged from development by Sun Microsystems in 1990

as a language to run household appliances. Then, it expanded to the Internet. In 1991 this

programming language, then called Oak, climbed the evolutionary latter to become object

oriented. In 1995, Oak began to receive a lot of attention and its name was changed to

Java.

Security is one of Java’s main advantages, and one of the reasons it has become so

popular. In Java, security is inherent. The language was designed this way so that devious

programmers could not create applets that could go into users’ computers and steal

valuable passwords. Java only permits applets to function within a sand box, thus, forcing

the applet to stay within the sandbox’s boundaries, inhibiting hacking. So unique and

reliable is this safety feature that it is used 1000 times more than Microsoft’s safety

device, Active X, which is built on mutual trust between internet users and providers.

One disadvantage to Java is that it is slower than C++. So, while its safety seems

to insure a temporary dominance of the Internet, it is by far less appealing for

applications delivered outside the net (CD roms, etc.)

There are two forms of Java that are of interest to the reader: applets and

applications. Applets are small bits of Java code embedded in HTML for web page

viewing. Applications, on the other hand, are stand alone programs, for example, HotJava

Browser.

Java Script

Most elements that appear on web pages are Java Script objects. The syntax of

Java Script is very similar to that of HTML, making it easy to learn. Furthermore, it is

parsed sequentially, meaning that the computer reads the language in sequence,

performing each step in the order in which it was written.

Java Script differs from HTML in that it is object oriented; while HTML

includes attributes within an element’s definition, Java Script links the object and the

property, allowing one to be changed. For example, if you have a document and you want

to change the background color, you would work with the document.bgcolor. Use Java

Script with single lines of code placed within anchor tags, or for more complex functions

contained within tags or before anchoring tags.

Java Script is also an object oriented programming language. Objects can be

maneuvered through what is called method acting, when actions methods perform. Some

methods work for any object and some work for just some objects. For example, let’s call

your object pete and your action walk. To make your object, pete, perform the action,

walk, you would write pete.walk. Properties can also be changed with method acting. So,

for example, if you would like to make your object, pete, red, you would code pete.red.

To perform both property and method, you could write pete.red.walk, or

object.property.method.

TOP BUSINESS SCHOOLS

Basic Scripts are easy to write with the knowledge of names of objects and

properties that modify them. Functions are long, complicated strings of Scripts, which

can be compiled with if/then operators such as && and parenthesis.

TOP BUSINESS SCHOOL offers you an unparallel opportunity to study at advance level, to work with in a challenging, stimulating and rewarding environment, to develop skills and competencies which will last throughout life, and most importantly, it will empower you intellectually to face the ever-evolving management world. http://www.govindam.org/
