About This Course

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.

Course Duration

45 Hrs.

At course completion

After completing this course, students will be able 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.
