Java SE 8 Programmer I (Oracle 1Z0-808)

The Java SE 8 Fundamentals certification training course is a beginner-level course aimed at professionals who are looking to learn how to program with Java and want to pursue the same as their career option. The course has all the fundamental knowledge and core concepts that the candidates will require to start their journey as Java programmers. The certification course is aimed at clearing all the basic concepts of Java and object-oriented programming that is done with Java.

Learning Objectives

A lot of core concepts are discussed in the certification training course for Java SE 8 Fundamentals, including the basics of Java as a programming language, what it is, how to develop simple code with it, and more. Some of the main parts and learning objectives of the Java SE 8 Fundamentals course are:

Learners will know how to create basic applications using Java constructs
Candidates of the certification course will also learn how to write error-handling code
They will learn how to write code that will include variables, conditional constructs, arrays, and loop constructs
Learners will understand how to use Java operators to manipulate string data and numeric data
They will be able to access the fields and methods of an object
They will also learn how to create various Java classes and learn how to use object references
They will be able to declare, override and invoke methods
Learners will know how to successfully handle a checked exception in Java applications
They will be able to implement a simple class hierarchy
They will be able to overload constructors and know how to encapsulate a class with the help of access modifiers

Course Content:

Module1: 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

Module2: WorDeclare 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 Integerking With Java Data Types

Module3: 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

Module4: Creating and Using Arrays

Declare, instantiate, initialize and use a one-dimensional array
Declare, instantiate, initialize and use multi-dimensional arrays

Module5: 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

Module6: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

Module7: 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

Module8: Handling Exceptions

Differentiate among checked exceptions, unchecked exceptions, and Errors
Create a try-catch block and determine how exceptions alter normal program flow
Create and invoke a method that throws an exception
Recognize common exception classes (such as NullPointerException, ArithmeticException, ArrayIndexOutOfBoundsException, ClassCastException)

Module9: 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
