Oracle Certified Associate (OCA) Java SE 8 Programmer

On this accelerated 3-day OCA Java SE 8 programming course, you'll be introduced to object orientated programming using the Java language.

Using our unique Lecture | Lab | Review technique, your expert instructor will guide you through creating command-line Java applications and creating conditional statements and loops. This technique, which combines both theoretical and practical tasks, will accelerate your learning as well as provide you with the hands-on experience you'll need to apply your skills to the real-world. You'll also learn how to:

• Apply Object-Oriented concepts such as Encapsulation, Inheritance and Polymorphism
• Use java types
• Manipulate Arrays and Collections
• Handle Exceptions
• Take advantage of new Java SE 8 features, such as Lambda expressions and Date/Time API

On this course, you will prepare for the Oracle Certified Associate Java SE 8 Programmer I (1Z0-808) exam, covered by your Certification Guarantee.

Achieving this certification is a prerequisite for attempting the Oracle Certified Professional Java SE 8 Programmer II. Save hundreds by combining both the OCA Java SE 8 Programmer and OCP Java SE 8 Programmer courses on the accelerated 7-day combined Oracle OCA and OCP Java SE 8 Programmer Certification course.

If you're a system administrator, project, web developer, program or technical manager looking to improve your programming skills, this course is ideal for you.

OCA Java SE 8 Programmer

Java Basics

• Define the scope of variables
• Define the structure of a Java class
• Create executable Java applications with a main method; run a Java program from the command line; including console output.
• Import other Java packages to make them accessible in your code
• Compare and contrast the features and components of Java such as: platform independence, object orientation, encapsulation, etc.

Java Data Types

• Declare and initialise 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.

Operators and Decision Constructs

• Use Java operators; including 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

Arrays

• Declare, instantiate, initialise and use a one-dimensional array
• Declare, instantiate, initialise and use multi-dimensional array

Loops

• 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

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; including impact on default 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

Inheritance

• Describe inheritance and its benefits
• Develop code that demonstrates the use of polymorphism; including overriding and object type versus reference type
• 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
• "Recognise common exception classes (such as NullPointerException, ArithmeticExcpetion, ArrayIndexOutOfBoundsException, ClassCastException)"

Java API Classes

• Manipulate data using the StringBuilder class and its methods
• Creating and manipulating 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 ArrayListof a given type
• Write a simple Lambda expression that consumes a Lambda Predicate expression

Before you attend this course, you should have at least six months’ programming experience in Java.

You will prepare for the following exam at the training centre during this course:
