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.
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 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.
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.
The goals for you are to: 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 StringBuilder 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
