Since its first appearance in 1995, Java has come a long way to gain enormous popularity. It is a general-purpose object-oriented programming language that is concurrent, class-based, and has very less implementation dependencies. The key benefits as listed by Java team are –
– Java is one programming language that is easy to learn and use. Even people from non-technical background won’t find Java difficult to master.
-It offers a realistic and clean approach to creating and using objects which increases the program modularity and reusability. The object model of Java can be easily extended; while it can have high performance non objects at the same time (primitive types).
– Robustness here is synonymous to reliability. To gain reliability, Java ensures error checking in early phases of program development. In Java, it is impossible to create bugs which are difficult to track down in rarely occurring run-time situations. One can predict how their code will behave in diverse conditions.
– Java allows one to write multithreaded programs, where several things can be performed simultaneously. Smoothly running and interactive systems can be created by the sophisticated solutions that Java provides for multi-process synchronization.
– One of the major problems that programmers faced before Java surfaced was that there was no guarantee whether a code written today would run tomorrow or not. OS and processor upgrades, changes in system resources and many other factors could cause a program to malfunction. Java designers built Java Virtual Machine as an attempt to impart longevity and portability to the code. Now the programmers can “write once; run anywhere, anytime, forever.”
– Java compiles the programs into Java bytecode, which is platform independent. This compiled code can then be executed on any system which supports JVM. The good part is that it doesn’t come at the cost of performance.
– Every time a normal program is downloaded from the Internet, there is an associated risk that the program might contain a virus, or any other harmful code. This malicious code is harmful as it gains unauthorized access to the system resources. For example, it might gather private information, like credit card numbers, passwords, bank account balances, and other content stored in your computer’s local storage.
While the applets in Java cannot launch such an attack as they are confined to the JRE, and they are not allowed to access other parts of the client computer. One can download applets with the confidence that security won’t be breached.
– Many different kinds of computers and operating systems connect to the Internet. So the Java programs need to execute on all of them. For instance, it won’t make sense to create different versions of applets for different kinds of machines. The same code should run on them, and Java proves to be the perfect way to generate portable executable code.
Along with the above stated benefits, Java is dynamic, distributed and a well designed language that provides an intuitive set of APIs. It enables writing a better code with lesser bugs and reduces the development time. It is a new age language, and due to its numerous benefits the number of developers using Java is ever increasing.
