  • Course details

    If you want to build applications for mobile devices, desktop computers, or the web, you need to know Java. This course provides the foundation for learning Java SE (Standard Edition), so you can build your first apps or start exploring the language on your own. Author David Gassner shows how to install Java and the IntelliJ IDEA IDE, and start working with variables, data types, keywords, and other critical language components. He also helps you control program flow with conditional logic and loops, store data with the Java Collections Framework, and understand how Java implements object-oriented coding principles such as inheritance and polymorphism.

Once you learn how to do one thing in Java, you know how to do it the same throughout the language because it never deviates from the way the language is architected. It's an object-oriented language so once you understand the principles of encapsulation, inheritance and polymorphism and how those are implemented in Java, you'll have a much better sense of how to architect your applications. For developers who've worked with C-style languages like C and C++, the syntax of Java is very familiar. Java was created to be robust and secure. It's robustness lies greatly in its object-oriented characteristics. Because you're designing everything as an object, everything has methods or functions and properties also known as fields that are members of classes. This lets you create your code in small chunks…
