Dated: 25-03-2019

Description


This Java SE 8 Fundamentals training introduces you to object-oriented programming using the Java language. Through hands-on exercises, you'll begin to build a baseline of knowledge to propel your career in development. The Oracle's Certified Associate Java SE Programmer 8 exam is the basic exam required to demonstrate a solid understanding of Java as a programming language and is a prerequisite to being a certified Programmer.


Topics

Inquiry Register

  1. 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.

2.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.  

3. Using 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 

4.Creating and Using Arrays 

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

5.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  

6.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; 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

7.Working with 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

8. 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)

9. Working with Selected classes from the Java API 

  • 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 ArrayList of a given type 
  • Write a simple Lambda expression that consumes a Lambda Predicate expression
