Beginning JavaFX™

Chapter 3. Data Types

JavaFX Script is a statically typed language, in which the type is associated with the variable and not the value. Hence it is capable of detecting type errors at compile time and thus allows many type errors to be caught early in the development cycle. Static type checkers evaluate only the type information that can be determined at compile time, but they are able to verify that the checked conditions hold for all possible executions of the program, which eliminates the need to repeat type checks every time the program is executed. This makes execution and storage more efficient and optimized.

Variable Declaration

Variable declarations in JavaFX Script are similar to those in Java itself. JavaFX Script is a case-sensitive ...
