Java: An Introduction to Problem Solving and Programming, 8th Edition

11.3 Graphics Supplement

This section introduces lambda expressions. Lambda functions are not limited to graphics and JavaFX, but we present them in the context of creating JavaFX event handlers. Lambda functions are useful in many other contexts, particularly for parallelizing operations to make a program run faster.
