# Description

If the body of the lambda statement contains only a single expression, the braces are optional. It can be reduced to a lambda expression.

This is comparable to if-statements or loops with a single expression inside their body, where braces are also optional.

# Benefits

This rule provides an easier-to read alternative to filter items in a list.

# Code Changes

public Function<Function, Function> f = (Function function) -> {
