Oracle Certified Associate, Java SE 8 Programmer is such a prestigious award that highlights your foundational Java skills. The certification provides a solid understanding of Java fundamentals, so you become adept with real-world responsibilities. It also prepares you for high-level tasks as a Java developer.
Who Can Opt for Certification?
If you want to dive deep into the Java programming language, then you are a suitable candidate for the Oracle Certified Associate, Java SE 8 Programmer certificate. This accreditation supports you in acquiring the right set of skills in working with the basic Java features, and to get it, you have to go through in-depth training and pass the Java SE Programmer I exam, or also known as 1Z0-808.
The recommended preparation course for 1Z0-808 is provided by Oracle. Though this is just optional, make sure you complete it, so you will have a more convenient and efficient learning path. In fact, this course is considered as a part of the official steps to fully become an OCA Java SE 8 Programmer. Along with that, itâ€™s a must to have prior hands-on experience and practical skills in Java programming. After accomplishing the first step, the next stage is about 1Z0-808 test itself.
What Are the Things You Need to Know about the Exam?
Oracle 1Z0-808 is a 150-minute exam that involves 70 questions of multiple-choice type. The passing score is 65%. The test centers on the fundamentals of Java, its core functionalities, and other relevant aspects. To better understand the content, Oracle offers a complete outline of the key topics you need to study thoroughly.
- The ABCs of Java
Before you get to the details, letâ€™s start with the basics. Recognize the scope of Java, its variables, features, and the entire structure itself. Learn how to build an executable Java app using the main method and then try running a Java program via the command line. Your knowledge must also cover the core Java components such as encapsulation, object orientation, and platform independence.
- Key Java data types
For the second part, you have to go through and initialize Java variables. Read up on the ways to differentiate between primitive and reference variables. In addition, itâ€™s an important skill to be able to read and write to object fields, explicate Objectâ€™s Lifecycle, and create a code using various wrapper classes.
- Java decision constructs and operators
The next major area that you have to master is the proper usage of operators through parentheses. You also need to assess the equality between strings and other related objects. In addition, itâ€™s relevant to be proficient in creating both if and if/else constructs and using switch statements.
Arrays are pivotal aspects in the Java language, hence the need to declare, instantiate, and set these accordingly. There are two main array types that need your attention â€• one-dimensional and multi-dimensional.
- Loop constructs
Practice how to utilize loop constructs efficiently. These include generating and using while loops, for loops, and do/while loops. Itâ€™s also a useful skill to know how to distinguish loop constructs as well as apply break and continue features.
- Methods and encapsulation
Refine your mastery in creating methods via return values and arguments. Likewise, static keywords are essential parts when using methods and fields. Subsequently, you have to work your way in learning overload constructors, access modifiers, and encapsulation. The last section focuses on how you regulate the impact upon primitive values and object reference as soon as they are passed into different methods.
- Inheritance and benefits
Handling inheritance takes up another part of the exam. This is where you develop codes that work with polymorphism and codes that override methods. It also provides you with insights on when to use casting, abstract classes as well as identifying the necessity of casting.
At this point, you will be working with exceptions, including checked and unchecked ones. Errors are also crucial aspects that you need to differentiate properly, along with common exception classes like NullPointerException, ClassCastException, and ArithmeticException. Some of the functions highlighted here are creating a try-catch block, invoking a method that throws an exception, and determining how these modify normal program flow.
- Selected classes
Java API is a vital facet that shouldnâ€™t go unnoticed. Itâ€™s a must that you train how to manipulate data via StringBuilder as well as manipulate strings and calendar data using java.time.LocalDate, java.time.LocalTime, java.time.LocalDateTime, java.time.Period, and the like. Using ArrayList and Lambda expression is important too.
What Happens After Passing the Exam?
Once you get a passing score in the Oracle 1Z0-808 exam, this means you have just ticked off the first part of the Oracle Java certification path. This entry-level accreditation leads to a more technical path. But whether or not you push through with the next certification step, having this is already an achievement. It serves as proof that you can effectively get the job done. Itâ€™s because the sections covered in the test arenâ€™t just any other topics. All these are relevant to keep your Java skills current. And during the process of studying for 1Z0-808, you actually gain necessary insights and hands-on experience that you can apply to your real-world job.
With validated skills, itâ€™s easy for you to move ahead of the game and carve your name in the chosen career. Henceforth, you become a sought-after Java professional that deserves higher financial compensation. To give you an overview, according to PayScale.com, Oracle Certified Associates takes home an average salary of $84k. Java developers, in particular, enjoy around $75k. Thatâ€™s pretty fascinating, right?
Whatâ€™s the Next Certification to Acquire?
OCA, Java SE 8 Programmer certification holders can further reinforce their skills with advanced certificates. For one, thereâ€™s the OCP, Java SE 8 Programmer, which gives you the opportunity to solidify your technical prowess in working with Java attributes, principally its Class Design, Stream API, I/O, Concurrency, Lambda Built-in, and such. Another option is the OCP, Java SE 11 Developer that centers on the facets of Java software development, specifically in the standard edition. This particular certification is an upgrade from OCP Java 6, 7, and 8.
