Java SE 8 Fundamentals

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.

Benefit

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. OBJECTIVE • 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
