Topics to Cover
Oracle 1z0-808 certification exam is based on the learnings, key topics, and activities encountered during oracle pieces of training and implementations.
Following are the major topics along with the sub-skills, a candidate should cover while preparing for the examination. These topics will give the candidates a clear view of which topics and skills inclusive, one should focus on for the certification.
Note: The list and details are not an all-inclusive content list. Oracle reserves the right to change and update the content (topics and sub-skills) at any point in time.

Inheritance Describe inheritance and its benefits Ability to use polymorphism Information about overrides methods Knowledge of different types of references Knowledge of different object types Ability to determine casting and its necessity in the code Knowledge of super and this to access objects and constructors Ability to use abstract classes and interfaces
Java API Ability to work with StringBuilder class and use its methods to manipulate data Ability to create and manipulate Strings Ability to create and manipulate calendar data using classes Ability to use and define an ArrayList Knowledge of simple Lambda expression and a Lambda Predicate expression
Java Data Types Ability to declare and initialize variables Knowledge of primitive data types and casting Knowledge of object reference variables and primitive variables and their differences Ability to read or write to object fields Ability to explain the lifecycle of objects including its creation, assignment, and garbage collection Knowledge of wrapper classes such as Boolean, Double, and Integer

Consider the following assumptions during the examination
Missing package and import statements if the sample code does not include package or import statements, and question does not explicitly refer to these missing statements. Then assume that all sample code is in the same package, or import statements to support them.
No file or directory path names for classes if the question does not state the file names or directory locations of classes, then assume that either All classes are in one file or Each class is contained in a separate file and all files are in one directory, whichever help in code to compile and run.
Unintended line breaks The sample code might have unintended line breaks. If you see a line of code that looks like it has wrapped, and this creates a situation where the wrapping is significant, assume that the wrapping is an extension of the same line, and the line does not contain a hard carriage return that would cause a compilation failure.
Code fragments A code fragment is a small section of source code that is presented without its context. In the case of Code fragments in question, assume that the necessary supporting code exists and the supporting environment fully supports the correct compilation and execution of code shown and its omitted environment.
Descriptive comments Take descriptive comments at face value and assume that the correct code exists, compiles, and runs successfully to create the described effect.
The candidate needs to go through and be proficient in every topic.
Questions in the exam are based on official training material provided by Oracle over different official platforms. Also the information in the following pieces of training is the source for the exam. Hence, candidates should complete the following training courses before appearing for the certification exam.
