::Analyzing C++ And Java: Exploring The Major Differences::

Most of the developers previously have experience with an object-oriented programming language such as C++. While you make the changeover to Java, you will come upon lots of differences, in spite of some deep similarities. In this article, we will discuss the major differences that C++ programmers should know.

As a C++ programmer, you must the fundamental idea of object-oriented programming, and the syntax of Java undoubtedly appears familiar to you. This fact is logically strong since Java was derived from C++. Still, there are a storming number of differences between C++ and Java.

Such differences are planned to be major improvements, and if you recognize the differences you'll see why Java is such a helpful programming language. This article will make clear the important features that differentiate Java from C++, just like your C++ Tutor does.

Speed: The biggest potential stumbling block is speed: interpreted Java runs in the range of 20 times slower than C. Nothing forecloses the Java language from being compiled and there are just-in-time compilers coming out at this writing that offer important speed-ups. It is not implausible that full native compilers will appear for the more accepted platforms, but without those there are classes of issues that will be unsolvable with Java because of the speed issue.

Comments: Java has both kinds of comments like C++ does.

Class: Everything must be in a class. There is no global function or global data. If you require the equivalent of globals, make static technique and static data within a class. There are virtually no structs or enumerations or unions, only classes.

Functionality: All method definitions are defined in the body of the class. Therefore, in C++ it would appear like all the functions are inlined, but they're not (inlines are noted afterward).

Class definitions: Class definitions are roughly the same form in Java as in C++, but there's no closing semicolon. Basically there are no class declarations of the form class foo, only class definitions.
class aType {
void aMethod( ) { /* method body */ }
}

Scope resolution: There's no scope resolution operator :: in Java. Java utilizes the dot for everything, but can get missing with it since you can describe elements only within a class. Still the method definitions must always happen within a class, so there is no requirement for scope resolution there either. A single place where you'll observe the difference is in the calling of static methods: you say ClassName.methodName( );. Besides this, package names are recognized using the dot, and to carry out a kind of C++ #include you use the import keyword. For example: import java.awt.*;. (#include does not straight map to import, but it has a related feel to it).

Primitive Type: Java, like C++, has primitive types for efficient access. In Java, there are char, boolean, byte, short, int, long, float, and double. The entire primitive types have specified sizes that are machine autonomous for portability. (This must have drive on performance, varying with the hardware.) Type-checking and type requirements are much strict in Java. For example:
- Conditional expressions can be only boolean, not integral.
- The result of an expression like X + Y must be used; you can't just say "X + Y" for the side effect.

Characters: The char type uses the international 16-bit Unicode character set, so it can automatically represent most national characters.

Strings: Static quoted strings are automatically converted into String objects. There is no autonomous static character array string similar to there is in C and C++.

Right Shift: Java adds the triple right shift >>> to act as a "logical" right shift by inserting zeroes at the top end; the >> inserts the sign bit as it shifts (an "arithmetic" shift).

Jobs For Java Professionals

The world is advancing at an immense speed in the contemporary times and thus there are various technological developments taking place each day. The IT sector is one arena where the burgeoning economy finds the best of its potential and aptitude employed. As the technology is the key element of almost every field of life, IT professionals that are well aware of technology and the latest software programs and computer languages are most sought.

The requirement for the qualified IT professionals who have the knowledge of the Java script and platforms has certainly become a paramount to a lot of multinational companies. It is so because Java has become a very crucial aspect of the web enabled solutions. Also, it is a significant part of the office technology as well and thereby the Java professionals who have ample knowledge in the field can be of great advantage in terms of expansion and success of any company. This immediate and rising need of the corporate world and the growing Java jobs implies that the Java experts and the graduates alike have separate market that largely favors them for their knowledge on Java over a long term.

What is best is that the Java professionals can choose working in a specific area or further general positions which fit the professional needs they have. The most crucial goal for the Java professionals is to locate the right kind of jobs in Java so that they can use their abilities to the maximum possible. The jobs in EJB or the Enterprise Javabeans and the jobs in JSP or JavaServer Pages are also on the rise as a lot of companies are looking for professionals who are experts in the EJB and the JSP skills.

One of the easiest ways to find the best of the Java jobs is by attending the job fairs that are held every now and then. These fairs can be a great opportunity for the Java professionals who are seeking jobs as many multinational companies come at the job fairs to recruit worthy and talented professionals of Java. This biggest advantage is that the professionals who are looking for quality and high paying jobs can actually speak in person with the representatives of various leading companies and submit their resume in hand. At times, if their candidature is considered, they can get interviewed and perhaps recruited on the spot.

ava jobs can also be found online where there are various recruiting websites. All what needs to be done is to submit the updated resume with the concerned website. This way all the companies that find the candidature of the Java professional suitable contact him/ her for the job. Online search for jobs saves a lot of time of the individual. But as the demand is high, the candidature is also top notch in the IT sector.
