Java SE 8 Programmer Certification (1Z0-808) Pass OCA Exam

Java SE 8 Programmer Certification (1Z0-808) Pass OCA Exam

By becoming a certified as an Oracle Certified Associate (OCA) Java 8 programmer you increase significantly your chances to get a job interview and a job as a Java programmer. Your CV will stand out of the crowd. All of the big companies pays a lot of attention for this certifications.

Regardless of the preparing strategy, such as books, only study materials, articles or trainings, all strategies need to be combined with mock exams!

Also, if you are quite comfortable with the Java language features, then yes, you can start your exam preparation with the mock exams. This will also help you to understand the types of questions to expect in the real certification exam.  The exam authors often use a lot of tricks to evaluate a candidate in the real certification exam. Similar tricky questions are present in this course also.

How many mock exams should you attempt before the real exam? Ideally, you should attempt at least five mock exams before the real exam. This course offers you 6. All the questions have the answers explained in detail.

The mock exams are structured similar with the real exam. Each question is tagged with the chapter that it belongs to, so it is easy to check what chapter you should focus more on!

Curriculum:

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; produce 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.

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

• Declare, instantiate, initialize and use a one-dimensional array

• Declare, instantiate, initialize and use multi-dimensional arrays

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

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
