Learn why Java can is most favorite programming language among new learners and developers along with how you can become certified Java Expert.
Students pursuing computer science know the need to learn Java programming language Java is a crucial subject and students learn Java with dedication. Java language is usually the most favorite subject of students. In the school curriculum, students are well known for the programming language C and C++ thus, it’s familiar for them to learn Java features. The reason Java is a popular programming language is it has an independent platform than other programming languages. Java is a high-level programming language. Originally developed by Sun Microsystems which released in 1995. A variety of platforms such as Windows, Mac OS, other versions of UNIX helps Java language to run independently.
Java is a general-purpose computer programming language. Java program can run on a computer with the installation of Java Run Environment, also known as JRE. JRE is available on every type of computer even on cell phones. Among developers, Java is the first preferred programming language and more than three billion devices run on Java as per the survey by Oracle. Java is such a unique language that all android and mobile applications and computer applications are built on Java. Some of the features of Java are:
- Java has a simple syntax that is why it is very simple to learn this programming language.
- Java is object-oriented and supports various OOP features like inheritance, abstractions, encapsulations, polymorphism.
- The reason bytecode can be carried over to any platform it is portable and known for its portability.
- In java, source code is compiled into bytecode which gives it a unique feature platform-independent.
- Java has no pointers; it has bytecode verifier programs and has a class loader that makes java secure language.
- Java has a neutral architecture that can run on any computer architecture as in Java code is compiled into bytecode.
- During runtime java architecture is adapted to reduce overhead. Bytecode generation makes it a high-performance feature than any other language.
- Java can be linked to new class libraries, objects, and methods dynamically. It supports functions from C and C++ which makes it a dynamic programming language.
- With Java distributed applications with RMI and EJB can be created.
- Multiple tasks can be handled simultaneously with improved user experience and productivity.
Some of the applications of Java are:
Mobile applications and android applications
Web server and application server
Desktop GUI applications
Following are the Java certifications which any person having an interest in Java programming language and wants to become certified Java professional can attain. Below sequence of certificates is as such that person cannot give Oracle Professionals Java Programmer exam without passing Oracle Certified Associate first. In the same manner, one has to qualified with the Oracle Professionals Java Programmer exam to give an exam for Oracle Master. Most Oracle certified exams cost 245$ and Rs.18,407 in India.
There are three types of Oracle Java Certifications mainly:
- Oracle Certified Associate – This exam has 70 numbers of questions. Duration of the exam is 120 minutes and the passing score is 63%
- Oracle Certified Professionals Java Programmer – This exam has 90 numbers of questions. Duration of the exam is 150 minutes and the passing score is 65%
- Oracle Certified Master – Duration to pursue this exam is six months from assignment purchase. The passing score is subject to the validation of assignment percent.
Competition in the market is tough to secure a job without verified Java certifications. Java certifications are the investment in yourself for a better career in the future. Oracle Java certification gives a person edge over the other candidates in terms of resume shortlist process or during the interview process.
