Lambdas
editLambdas
editLambda expressions and method references work the same as in Java.
list.removeIf(item -> item == 2); list.removeIf((int item) -> item == 2); list.removeIf((int item) -> { item == 2 }); list.sort((x, y) -> x - y); list.sort(Integer::compare);
You can make method references to functions within the script with this,
for example list.sort(this::mycompare).
