Java programmer certifications are designed to tell would-be employers whether you really know your stuff, and cracking the OCA Java SE 8 Programmer Certification is not an easy task. if you want to pass the exam the first time with a score that you can be proud of. You need to take this course, that will help you to understand the certification process so that you’re ready for the challenging questions you’ll face in 1Z0-808 the exam. This course provide detailed explanations, including why options are correct or incorrect. Mark your incorrect answers and identify the sections that you need to reread.
The Oracle Certified Associate (OCA) Java SE 8 Programmer I exam (1Z0-808) covers the fundamentals of Java SE 8 programming, such as the structure of classes and interfaces, variables of different data types, methods, operators, arrays, decision constructs, and loops. The exam includes handling exceptions and a few commonly used classes from the Java API like String, StringBuilder, and ArrayList. This exam doesn’t include a lot of Java 8–specific language features. It includes an introduction to functional-style programming with lambda expressions. It partially covers the new Date and Time API.
This exam is one of two steps to earning the title of Oracle Certified Professional (OCP) Java SE 8 Programmer. It certifies that an individual possesses a strong foundation in the Java programming language.

■ Use a switch statement
✓ Using Loop Constructs
■ Create and use while loops
■ Create and use for loops including the enhanced for loop
■ Create and use do/while loops
■ Compare loop constructs
■ Use break and continue
✓ Working with Inheritance
■ Describe inheritance and its benefits
■ Develop code that makes use of polymorphism; develop code that overrides methods; differentiate between the type of a reference and the type of an object
■ Determine when casting is necessary
■ Use super and this to access objects and constructors
■ Use abstract classes and interfaces
✓ Working with Selected classes from the Java API
■ Manipulate data using the StringBuilder class and its methods
■ Create and manipulate Strings
■ Create and manipulate calendar data using classes from java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, java.time.format.DateTimeFormatter, java.time.Period
■ Declare and use an ArrayList of a given type
■ Write a simple Lambda expression that consumes a Lambda Predicate expression
✓ Creating and Using Arrays
■ Declare, instantiate, initialize and use a one-dimensional array
■ Declare, instantiate, initialize and use multi-dimensional arrays
✓ Working with Methods and Encapsulation
■ Create methods with arguments and return values; including overloaded methods
■ Apply the static keyword to methods and fields
■ Create and overload constructors; differentiate between default and user defined constructors
■ Apply access modifiers
■ Apply encapsulation principles to a class
■ Determine the effect upon object references and primitive values when they are passed into methods that change the values
✓ Handling Exceptions
■ Differentiate among checked exceptions, unchecked exceptions, and Errors
■ Create a try-catch block and determine how exceptions alter normal program flow
■ Describe the advantages of Exception handling
■ Create and invoke a method that throws an exception
■ Recognize common exception classes (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException)
Frequently Asked Questions (FAQs)
HOW DO I KNOW WHEN I AM READY FOR THE EXAM?
You can be sure about your exam readiness by consistently getting a good score in those practice exams. Generally, a score of 80% and above in approximately three to five practice exams attempted consecutively will assure you of a similar score in the real exam.
HOW MANY MOCK TESTS SHOULD I ATTEMPT BEFORE THE REAL EXAM?
Ideally, you should attempt at least five mock exams before you attempt the real exam. The more the better!
CAN I START MY EXAM PREPARATION WITH THE PRACTICE EXAMS?
If you are quite comfortable with the Java language features, then yes, you can start your exam preparation with the mock exams. This will also help you to understand the types of questions to expect in the real certification exam.
SHOULD I REALLY BOTHER GETTING CERTIFIED?
Yes, you should, for the simple reason that employers care about the certification of employees. Organizations prefer a certified Java developer over a noncertified Java developer with similar IT skills and experience. The certification can also get you a higher paycheck than uncertified peers with comparable skills.
