Getting Started with Java: Variables & Primitive Types

IN THIS COURSE

• 1.  Course Overview
  2m 6s
  In this video, you’ll learn more about your instructor and this course. In this course, you’ll learn Java variables and primitive data types of Java. You’ll create variables in your program and learn the effects of static typing in Java. You’ll also work with various primitive data types in this language from numeric types to text representations in the form of strings. You’ll also cover the use of an ordered collection of data.

• 2.  Declaring Variables in Java
  12m 16s
  In this video, you’ll watch a demo. You’ll learn the definition and use of variables. You’ll learn a variable is effectively a container for a value. And that value can keep changing. First, for this demo, you’ll clean out the console. Then, you’ll replace the comments within the main function with two lines of code. FREE ACCESS
• 3.  Printing Strings with the format Method in Java
  11m 45s
  In this video, you’ll watch a demo. You’ll move along to other forms of variable declarations. First, you’ll replace the contents of the main method with the code onscreen. You’ll then declare a variable called varString. You’ll see this is a type of string with an uppercase S. A string in the context of Java is any sequence of letters, numbers, and uppercase characters. They are usually defined inside two double quotes. FREE ACCESS
• 4.  Exploring Primitive Data Types in Java
  9m 59s
  In this video, you’ll watch a demo. You’ll explore more data types supported by Java. You’ll bring up the Project pane in IntelliJ in order to create a new Java source file within the source folder. You’ll right-click, head over to New, and choose the option of a Java Class. You’ll specify a name for this class, calling it DataTypes. Hit Enter and a new source file called DataTypes.java will be created. FREE ACCESS
• 5.  Working with Integers, Floats, and Doubles in Java
  8m 7s
  In this video, you’ll watch a demo. Here, you’ll explore primitive data types in Java in more detail, starting with an integer. You’ll minimize the console and then clear out the contents of the main method. Then, you'll paste in two lines of code. Next, you’ll head over to Edit Configurations. Then, you’ll change the name of this run configuration called RunDataTypes to DataTypes. FREE ACCESS
• 6.  Working with Byte, Short, and Char Types in Java
  8m 13s
  In this video, you’ll watch a demo. You’ll continue working with the different primitive data types in Java. First, you’ll clear out the contents of the main function. Then, you’ll define a byte variable called varByte. You’ll assign a value of 30 to it, and then print it out to the console. You’ll see a byte can store negative values as well. Specifically negative whole numbers. FREE ACCESS
• 7.  Strings and Arrays in Java
  12m 37s
  In this video, you’ll watch a demo. You’ll work with some non-primitive types, specifically strings. Strings are a fundamental data type in any programming language. However, the way they’re used in Java, they include a lot of complexity. This is what you’ll explore in this video. You’ll see that within the data types class, you’ll need to modify the main method so that a string is in use. FREE ACCESS
• 8.  Course Summary
  1m 59s
  In this video, you’ll summarize what you’ve learned in the course. You’ve learned more about the various primitive data types in Java. You created variables in your program and learned the effects of static typing in Java. You also learned about the various numeric types, such as integers and doubles, which have their own benefits and limitations. You also explored different text representations in the form of characters and Java strings. FREE ACCESS
