• Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.

 Working With Java Data Types 

• Declare and initialize variables (including casting of primitive data types)
• Differentiate between object reference variables and primitive variables
• Know how to read or write to object fields
• Explain an Object’s Lifecycle (creation, “dereference by reassignment” and garbage collection)
• Develop code that uses wrapper classes such as Boolean, Double, and Integer

 Using Operators and Decision Constructs 

• Use Java operators; use parentheses to override operator precedence
• Test equality between Strings and other objects using == and equals ()
• Create if and if/else and ternary constructs
• Use a switch statement

 Creating and Using Arrays

• 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 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

 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

 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)

 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

Practice tests are randomized to give a real examination feel. All topics listed above are divided appropriately in 4 tests consisting 70 questions each i.e., 280 questions in total and 2 bonus tests containing 72 questions each (144 bonus questions), which makes total 424 unique questions. Questions are designed based on real examination questions in terms of pattern and complexity.

Explanation of all the correct answers is also provided for reference and understanding. Relevant hints and how to approach a question in real examination setting is also provided in explanation.

Completing all the tests successfully will boost your confidence to attempt Oracle Certified Associate (OCA) examination.

More information on detailed curriculum and assumptions to be followed for examination are available on oracle certification page.

NOTE: Each practice test of this course contains questions on all the exam topics, similar to what is expected in real exam. But if you prefer to solve topic-wise questions, then enroll in my other course titled “Java Certification – OCA (1Z0-808) Topic-wise Tests [2022]”, which contains the same questions arranged in topic-wise manner.

Disclaimer: These questions are not real examination questions / dumps. These questions  are created to evaluate your preparation for certification exam. 

So, grab a cup of coffee or your favourite drink and test your Exam Preparation.

Features of Practice Tests:

• You can pause the test at any time and resume later.
• You can retake the test as many times as you would like.
• The progress bar at the top of the screen will show your progress as well as the time remaining in the test. If you run out of time, don’t worry; you will still be able to finish the test.
• You can skip a question to come back to at the end of the exam.
• You can also use “Mark for Review” to come back to questions you are unsure about before you submit your test.
• If you want to finish the test and see your results immediately, press the stop button.
