Java SE 11: Introduction to Java SE & the NetBeans IDE
Discover how to get up and running with the Java Development Environment and with the NetBeans IDE to create Java programs. During this course you will discover the purpose of a computer program and the nature of platform-dependency. Learn about Java classes, Java's program structure, and key Java language features. Confirm your Java Development Environment. Install and verify the Java Development Kit (JDK) on Linux. Compile and run a Java program from the command line. Install and explore the Netbeans IDE. Employ NetBeans to create a Java project and class and add a package to it. Write a main method. Use System.out.println and System.err.println to write to the console. Finally, conclude by recognizing NetBeans syntax errors.

Java SE 11: Expressions, Arrays, & Loops
Discover how to work with branching and Boolean expressions using if/else statements in Java.During this course, you will examine what a Boolean expression is, and how create IF/ELSE statement branches. Topics include the following: how to employ Boolean Operators, identifying the results of various Boolean expressions, how to create simple and nested IF/ELSE statements, and study the characteristics of arrays. Other subjects covered include how to declare and initialize arrays, access array elements and set their values, loop array elements, and create a FOR loop to print the elements of an array. Finally, you will learn how to use the BREAK and CONTINUE functions to control program flow in a loop.

Java SE 11: Objects & Classes
Explore the essential elements of Java objects, classes, references and methods. During this course, you will discover the characteristics of a Java object. Define Java object components and properties. Use object references. Work with two References for one object. Study how an array of objects is stored in memory. Describe the basic forms of a constructor and a method. Other topics include how to create a class that implements a constructor, how to define method parameters, employ method overloading, and implement methods that return values of a specified type. Finally, you will study how to distinguish between local and instance variables.

Java SE 11: Encapsulation
Explore object-oriented programming concepts and techniques, in Java. During this course, you will discover various static methods and variables and explore a number of topics. These include the following: how to create and access static members, how to employ constants to represent unchangeable values, how to change numeric variable types through promotion and casting, and convert data values. Other topics include how to convert strings to their primitive numeric types, ciscover access control, and how to distinguish between the public interface and the internal workings of a class. Next, you will learn how to use public and private access modifiers, study encapsulation with object-oriented design, and create class setter methods with value checking. As you progress, other key areas include how to add method parameters to overload a constructor, how to pass an Object Reference, and pass a value. Finally, you will learn how to reassign a reference value in a method.

Java SE 11: Strings & Primitive Data Types
Explore working with strings in Java, including the use of mutable strings through the StringBuilder class. In this course, you will discover the nature and use of strings and primitive data types, in Java. Observe how to compare and sequence strings, through equality tests and lexicography. Discover mutable strings, the advantages of string builder, and how to concatenate strings. Next, split a string via a regular expression, and learn how to split a paragraph of text into words in a string and iterate over individual words.Other topics include how to consider primitive data types, how to perform the standard modulus mathematical operation on an integer. Finally, you will use combined assignment operators to abbreviate common operations.

Java SE 11: JDK Objects & Nested Loops
Examine the nature and use of Java Development Kit (JDK) objects and nested loops. During this course, you will explore JDK API documentation to learn about Java class libraries. See how to display a date with the LocalDateTime object, with the Java DateTimeFormatter, or with the calendar. Parse a localized date and convert it to ISO format. Parse the ARGS array, and use it in the main method, to accept command line arguments. Observe how to use a WHILE loop construct and nest a WHILE loop. Run a standard FOR loop and nest a FOR loop within the body of another loop.

Java SE 11: Flow Control & Debugging
Discover how to implement flow control using ternary, if/else, and switch statements in Java. During this course, you will start by exploring the use of two dimensional arrays, enumerated types, and the debugging features of the NetBeans IDE. Next, see how to use a ternary conditional statement, and how to chain IF and ELSE constructs together. As you progress you will discover how to implement a SWITCH statement, and other key topics such as how to create a SWITCH statement based on an enumerated type. You will also learn how to employ the Eclipse debugger, set debugging breakpoints that halt program execution, and let you step through the code. Finally, you will inspect the value of variables to debug a program.
