# Java SE 8 Fundamentals ## Java SE 8 Fundamentals ### Overview This Java SE 8 Fundamentals training introduces you to object-oriented programming using the Java language. The course will prepare you for the Oracle Certified Associate Java SE 8 Programmer Certification. Through hands-on exercises, you'll begin to build a baseline of knowledge to propel your career in development. **Learn To:** * Use Java programming language constructs to create a Java technology application. * Use decision and looping constructs and methods to dictate program flow. * Understand basic object oriented concepts such as inheritance, encapsulation, and abstraction. Use and manipulate object references, and to write simple error handling code. * Use the new Java SE 8 `java.time` and`java.time.format` packages to format and print the local date and time. * Specify a data modification by passing a predicate lambda expression to the Collections class. ### Duration The course is conducted full time over 5 days. ### Programming Experience No prior experience is required to take this course. This is a beginners course and the first course in your jouney as a Java Developer. ### Technical Skill A mastery of computer skills is required to take this course. You should be comfortable writing a lot of code fast. ### Private Training We offer the training privately. A minimum of 4 delegates is required to schedule the course privately. The course can be taken onsite or on our premises. There is no fixed date the course will run, we work your team to find a suitable date to schedule the course. ### Public Training This course is also offered publicly. Due to complexities in scheduling, there is no set date to run the course. The course will be scheduled to run once we have 4 delegates. The course runs in our offices in Johannesburg and Cape Town. #### **Benefits to You** By enrolling in this course, you'll expand your knowledge of Java SE 8, while building your Java skill set. You'll build a solid basis in the Java programming language upon which to base continued work and training. #### **Audience** * Application Developers * Developer Project Manager * System Administrator * Team Leader * Technical Administrator * Technical Consultant * Web Administrator #### **Course Objectives** * Write Java code that uses variables, arrays, conditional and loop constructs * Manipulate primitive numeric data and string data using Java operators * Create Java classes and use object references * Access the fields and methods of an object Manipulate text data using the methods of the String and String Builder classes * Use casting without losing precision or causing errors * Declare, override, and invoke methods * Access and create static fields and methods * Use classes from the java.time and java.time.format packages to format and print the local date and time * Encapsulate a class using access modifiers and overloaded constructors * Define and implement a simple class hierarchy Demonstrate polymorphism by implementing a Java Interface * Use a Predicate Lambda expression as the argument to a method * Handle a checked exception in a Java application ## **Course Curriculum** **What Is a Java Program?** Introduction to Computer Programs Key Features of the Java Language The Java Technology and Development Environment Running/testing a Java program **Creating a Java Main Class** Java Classes The main Method **Data In the Cart** Introducing variables Working with Strings Working with numbers Manipulating numeric data **Managing Multiple Items** Working with Conditions Working with a List of Items Processing a list of items **Describing Objects and Classes** Working with objects and classes Defining fields and methods Declaring, Instantiating, and Initializing Objects Working with Object References Doing more with Arrays Introducing the NetBeans IDE Introducing the Soccer League Use Case **Manipulating and Formatting the Data in Your Program** Using the String Class Using the Java API Docs Using the StringBuilder Class More about primitive data types The remaining numeric operators Promoting and casting variables **Creating and Using Methods** Using methods Method arguments and return values Static methods and variables How Arguments are Passed to a Method Overloading a method Using Encapsulation Access Control Encapsulation Overloading constructors **More on Conditionals** Relational and conditional operators More ways to use if/else constructs Using Switch Statements Using the NetBeans Debugger **More on Arrays and Loops** Working with Dates Parsing the args Array Two-dimensional Arrays Alternate Looping Constructs Nesting Loops The ArrayList class **Using Inheritance** Overview of inheritance Working with subclasses and superclasses Overriding methods in the superclass Introducing polymorphism Creating and extending abstract classes Using Interfaces Polymorphism in the JDK foundation classes Using Interfaces Using the List Interface Introducing Lambda expressions **Handling Exceptions** Handling Exceptions: An overview Propagation of exceptions Catching and throwing exceptions Handling multiple exceptions and errors --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
