I’ve wet my feet a little on the Java package [java.util.function](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/function/package-summary.html) by instantiating a [[u]Predicate[/u]](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/function/Predicate.html) and passing it as an argument at these 2 old sketch links below: 🤪

1. [Querying ArrayList - Processing 2.x and 3.x Forum](http://Forum.Processing.org/two/discussion/21761/querying-arraylist#Item_2)
2. [Forum.Processing.org/two/discussion/22823/how-to-implement-this-method#Item\_2](http://Forum.Processing.org/two/discussion/22823/how-to-implement-this-method#Item_2)

Of course it’s not even close to an actual lambda `->` syntax. But it’s as far as we can go under the PDE. 🙄
