Java is a computer language that was primarily designed to be simple and also architecturally neutral. During its early years, the language was promising but at that time there was still no market for it. In 1995, what the developers did was to introduce Java at the Sun World exhibition. Programmers were enthusiastic about the simple language and the richness of its library. This meant that more and more portable programs could be written that could bypass proprietary operating systems.
Java offers micro and enterprise editions of its library which make the programmers comfortable on any hardware. There is a vast range of this from simple gaming devices to the largest internet providers. In this article, what would be focused on would be the benefits of Java’s superior performance and its security features.
Java programs are grouped to a portable intermediate form that we know now as byte codes. This is similar but of a newer form of the machine-language instructions. Java Virtual Machine has a program that could be used so as to interpret these portable byte-code commands. Make-up and form of Java programs meant that they process at a higher speed compared to scripts and programs which are written in interpreted languages. The only problem here is that they are somewhat slower than C and C++ programs.
There is one thing that users must remember, that although Java programs are compiled to byte code, the interpreted byte codes does not cover up the totality of Java platforms. Portions concerned with intensive computations of the Java platform like string-manipulation methods are being used with older versions of machine code could be implemented using the older version of the machine code to ensure its efficiency.
It is true that the earlier versions of Java suffered from some problems with its performance. Through the years, the program has greatly improved. Almost every year, it comes with a new release that further progresses the speed of Java VM. Its performance is no more its biggest problem.
The VM has undergone significant changes to make it highly developed and optimized. Many developments include a just-in-time compiler; this development is capable of converting Java byte codes to an older version of machine commands. Java programs are also equipped with JIT compilers; this helps the system perform at speeds that are as good as or even better than C and C++ applications.
Many programmers avoided it before due to glitches in performance. With the advances made in Java 1.2, more and more use it. It is a perfect combination of performance and manageability.
The language and the platform of Java were designed from the ground up with security as one of the primary design concepts. Users are allowed to download unsecure codes over the network with the help of the Java platform. It is still safe to use because you could run it in a secure environment. At this state, the host system will not be affected or infected by a virus and many other sorts of problems. The Java platform’s capacity by itself makes the system one of a kind.
By the introduction of Java 2 Platform, security models went up a notch. This development made the security levels and restrictions highly configurable and broadens them further than just being applets. With Java 1.2, all the Java codes like the applet, the JavaBeans component, or complete applications can be run with highly restricted permissions and helps protect the host system from being harmed by these.
Java’s language and platform’s security features underwent thorough analysis by various security experts that came from all parts of the globe. This ensured the security. Some security-related bugs were found in the system and swiftly fixed. This made a big noise especially when a new security bug is found. Other mainstream platforms available in the market are not able to create security guarantees that Java could offer. This is one big reason behind its popularity.
Even if Java holds the best security promises there are still some features that need improvement. Even if that is the case, Java gives the assurance that it is well suited to be used on practical and simple every day applications. In the market, you will not find other alternatives that are up to par with what Java can offer and do.
