Java SE: Programming I

This entry-level course is aimed at programmers who are new to Java and who need to learn its concepts, language constructs, and data types. Included in the agenda are topics on exception handling, lambda expressions, and modular programming.

The course is designed for programmers who will apply these language skills to develop programs using the latest major versions of the JDK, currently Java 11. Students practice the skills learned in each lesson through hands-on labs.
------------------------------------------------------------
Course Objective

Write Java code that uses variables, arrays, conditional and loop constructs of achieve program objectives
Identify modular programming principles
Access and create static fields and methods
Encapsulate a class using access modifiers and overloaded constructors
Manipulate numeric, text, and string data using appropriate Java operators
Set environment variables to allow the Java compiler and runtime executables to function properly
Create simple Java classes and use object references to access fields and methods in a class
Demonstrate polymorphism by implementing a Java interface
Handle a checked exception in a Java application
Use a Predicate Lambda expression as the argument to a method
Define and implement a simple class hierarchy that supports application requirements
