Description
Great Java: Level 1 will teach you the fundamentals of Java, from the basics of compilation through methods, objects, and the key concepts of good programming. By the time you're through these lessons, you'll be programming, and programming well.
Throughout the course, you'll progressively learn to code and compile programs, work extensively with text, and declare, convert, and cast between data types. You'll also read files, get user input, and build arrays, including multi-dimensional arrays. Finally, you'll move into objects, modeling your data and behavior into core Java structures.
When you buy Great Java: Level 1, you get access to an entire video library of lessons-including lessons that aren't available yet! Here's the scoop: we're continually adding new sections in Level 1 that take you further into Java. We're also updating existing lessons and creating new ones in response to your questions, along with special "challenge lessons" that will test your skills. All of this is yours with Great Java: Level 1.

32.
How Strings Work
2 minutesYou've seen how Java works, and you've seen your program as a network of roads. But how do strings work? How does Java "see" your strings? Learn all that and more in this visual presentation of strings. -
33.
Your Code Must Deal With Change

Java Deals with Data Types
4 minutesJava thinks about your text, your numbers, your data, in terms of types of data. So your number is an int or a float, your text is a String, and so forth. In this lesson, you'll take control of those data types, and see why Java can get confused... even if you're not. -
40.
Convert Data Types with Casting
4 minutesWhat if you need a piece of text treated as a number? Or a decimal treated as an integer (with some loss of precision)? In those cases, you need to "force" Java to switch between data types. This lesson gives you the tools to do just that. -
41.
Use Double for Decimal Types
4 minutesThere's more than one data type that works for decimal values. Learn why double is a good, simple choice for your basic decimal needs. -
42.
There's Still Plenty to Learn
1 minuteSo what about data types we haven't covered? What about that main() method? What about all those things you're not even sure you need to know? Get a taste of what's to come, and why it's okay that you don't know everything yet.
