Java is general purpose objected oriented programming language. Java was originally developed by James Gosling at Sun Microsystems. The Sun microsystem has been acquired by Oracle Corporation. The developer can learn the java programming language from oracle java tutorial web. The internet has a lot of information about the java languages. If the developer knows the java programming language fundamentals, they can start preparing the certification. The developer cannot get the job based on the certification. Some companies may give preference to the certified programmer. The certification helps career growth in the software industry. It gives the confidence to the developer. The Certification validate the different topics from the programming language depends on the certification track. The developer can read the tutorial and technical content from the internet. They can also buy and study the technical books for preparing the certification.
Java supports three different version Java SE, Java EE and Java ME. The java standard edition (Java SE) includes a complete JRE plus tools for developing, debugging, and monitoring Java applications. Java Enterprise Edition (Java EE) provides an API and runtime environment for developing and running enterprise software, including network and web services, JSP, JSP, Servlet and other large-scale, multi-tiered and secure network applications. Java Micro Edition (Java ME) provides a flexible environment for applications running on embedded and mobile devices in the Internet of Things.
Oracle provides different certification in java programming language. The user can find more details on the following pagehttps://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=651#5
The Beginner can start from Java Foundations (novice-level exam) (Exam Number: 1Z0-811). It starts with basic information about the java programming language.
Java SE 8 Programmer I (Exam Number: 1Z0-808) and Java SE 8 Programmer II (Exam Number: 1Z0-809) provide more depth about the java programming language. Each certification cover the set of topics. If the programmer wants to start to prepare the certification, the programmer should concentrate all the areas. If the developer good in one area and do not concentrate on another area may fail in the examination. The developer may get dumps (which comes from the previous exam).

If the developer has more experience in the java in all areas including the Design and architect the application, the developer can start Java EE 6 Enterprise Architect Certified Master. This certification contains multiple levels and may require a lot of preparation and skills. The developer can start after getting some experience in software industry. Careerdrill recommends starting around 10 years experience candidate. The developer can get more details from the following location.
Note: We have discussed the core and J2EE java certification path. The developer can also look the other products like WebLogic, SOA, and JDeveloper which related to java programming language based on the developer interest.
