  • 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.

Both syntax errors, which you must deal with before you can compile and run your application, and run time exceptions. Those exceptions that occur while the application is running. In the empty made method, I'll start by introducing a syntax error. If you've been coding for any amount of time, I'm sure you've seen some of these. I'll declare a String that I'll name s. And I'll try to assign it to the keyword Null. Now, I'll intentionally misspell it. The keyword Null in Java is all lower case. When I type it with an upper case in, and then I try to run the application, the application doesn't even compile. Instead I get a syntax error, telling me that the compiler can't find the symbol.
