I failed OCP examination

[Mike Savvy]

With no practical experience in programming on the job (but with college programming courses and independently studying and practicing) I started to learn for OCP certification in August. I did many pauses where I tried to learn SQL also (I have examination appointment tomorrow). I learned with book from J. Boyarsky, but I din't master to read the whole book, just the first half or less. It was very implex to me to understand the language. I think I undersdood less than a half or less of what I mastered to read. Also in August I started a job as a working student in standard software development but it looks like I don't understand nothing of what I have to do. So there are my 33%. I will try again in one year.

Thank you Campbell for feedback!
I do not worry because of that score

In life - which is long - you will have many successes, and some failures, too. Yes, it is LIFE.

Between, I planning to take the exam in future too. Is there any age limit ?

I'm not sure if it was a limit, but when you start identity verification before exam, you should check in the field that you are 18 or older. Then you should take photo of you, photos of your room where you will take exam and photo of driver license or identity card.

Sorry to hear about your score. I am sure you will crack it next time if you study seriously.
Please do share your feedback about the exam such as what topics you found tough to answer. Were you able to score more than passing marks on the mock exams?

classes

local class, nested class, and anonymous inner class
l Create worker threads using Runnable, Callable and
use an ExecutorService to concurrently execute
tasks

JDBC API including the Driver, Connection,
Statement, and ResultSet interfaces and their
relationship to provider implementations
l Develop code that uses Stream data methods and
calculation methods
l Develop code that uses primitive versions of
functional interfaces
l Develop code that uses the Optional class
l Develop code that uses the UnaryOperator interface
l Develop code to extract data from an object using
peek() and map() methods including primitive
versions of the map() method
l Identify the components required to connect to a
database using the DriverManager class including
the JDBC URL
l Implement inheritance including visibility modifiers
and composition
l Iterate using the forEach methods of Streams and
List
l Override the hashCode, equals, and toString
methods from the Object class
l Read and set the locale by using the Locale object
l Read and write data from the console
l Search for data by using search methods including
findFirst, findAny, anyMatch, allMatch, and
noneMatch
l Sort a collection using Stream API
l Submit queries and read results from the database
including creating statements, returning result sets,
iterating through the results, and properly closing
result sets, statements, and connections
l Test invariants by using assertions
l Use Autoclose resources with a try-with-resources
statement
l Use BufferedReader, BufferedWriter, File,
FileReader, FileWriter, FileInputStream,
FileOutputStream, ObjectOutputStream,
ObjectInputStream, and PrintWriter in the
java.iopackage.

l Use built-in interfaces included in the
java.util.function package such as Predicate,
Consumer, Function, and Supplier
l Use enumerated types including methods and
constructors in an enum type
l Use flatMap() methods in the Stream API
l Use java.util.Comparator and java.lang.Comparable
interfaces
l Use method references with Streams
l Use parallel Streams including reduction,
decomposition, merging processes, pipelines and
performance
l Use synchronized keyword and
java.util.concurrent.atomic package to control the
order of thread execution
l Use the Files class to check, read, delete, copy,
move, manage metadata of a file or directory

directory paths
l Use the java.util.concurrent collections and classes
including CyclicBarrier and CopyOnWriteArrayList
l Use try-catch and throw statements
l Work with dates and times across timezones and
manage changes resulting from daylight savings
including Format date and times values
