the intro you did

> [Sam Pottinger](https://github.com/sampottinger/processing) has done an amazing job in updating processing, not only to update to OpenJDK11, but also to support java 8 syntax in the processing ide. I’m sure he would welcome your support. Here is an example using lambda syntax in the processing ide. interface MyFunction { float calculate(float x); } float[] values = new float[2]; void setup() { // lambda expression to define the calculate method MyFunction doubling = (float x)-\>x \* 2; values[0] = doubling.calculate(5); …

was good for understand the basics

here testing the second example, get
