OCPJP - I SE 11 1Z0-815 Exam Topics	OCAJP 8 1Z0-808 Exam Topics
Understanding Java Technology and environment Describe Java Technology and the Java development environment Identify key features of the Java language	Java Basics Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.
Creating a Simple Java Program Create an executable Java program with a main class Compile and run a Java program from the command line Create and import packages	Java Basics Create executable Java applications with a main method; run a Java program from the command line; produce console output Import other Java packages to make them accessible in your code
Describing Objects and Classes Define the structure of a Java class Read or write to object fields Declare and instantiate Java objects, and explain objects' lifecycles (including creation, dereferencing by reassignment, and garbage collection)	Java Basics Define the structure of a Java class Working With Java Data Types 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
Working With Java Primitive Data Types and String APIs Declare and initialize variables (including casting and promoting primitive data types) Identify the scope of variables Use local variable type inference Create and manipulate Strings Manipulate data using the StringBuilder class and its methods	Java Basics Define the scope of variables Working With Java Data Types Declare and initialize variables (including casting of primitive data types) Differentiate between object reference variables and primitive variables Develop code that uses wrapper classes such as Boolean, Double, and Integer Working with Selected classes from the Java API Manipulate data using the StringBuilder class and its methods Create and manipulate Strings

Using Operators and Decision Constructs Use Java operators including the use of parenthesis to override operator precedence Use Java control statements including if, else, break and continue Create and use do/while loops, while loop, and for looping statements including nested loops	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 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
Creating and Using Methods Create methods and constructors with arguments and return values Create and invoke overloaded methods Apply the static keyword to methods and fields	Working with Methods and Encapsulation Create methods with arguments and return values; including overloaded methods Determine the effect upon object references and primitive values when they are passed into methods that change the values Apply the static keyword to methods and fields Create and overload constructors; differentiate between default and user defined constructors
Applying Encapsulation Apply access modifiers Apply encapsulation principles to a class	Working with Methods and Encapsulation Apply access modifiers Apply encapsulation principles to a class
Reusing Implementations Through Inheritance Create and use subclasses and superclasses Create and extend abstract classes Enable polymorphism by overriding methods Utilize polymorphism to cast and call methods, differentiating object type versus reference type Distinguish overloading, overriding, and hiding	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
Programming Abstractly Through Interfaces Create and implement interfaces Distinguish class inheritance from interface inheritance including abstract classes Declare and use List and ArrayList instances Understanding lambda Expressions	Working with Inheritance Use interfaces Working with Selected classes from the Java API Declare and use an ArrayList of a given type Write a simple Lambda expression that consumes a Lambda Predicate expression
