Example
Add 1 to every number in a list:
import java.util.LinkedList;
public class Main {
public static void main(String[] args) {
LinkedList<Integer> numbers = new LinkedList<Integer>();
numbers.add(5);
numbers.add(9);
numbers.add(8);
numbers.add(6);
numbers.add(1);
numbers.replaceAll( n -> n + 1 );
System.out.println(numbers);
}

Definition and Usage
The replaceAll() method replaces every item in a list with the result of performing an operation on the item. The operation can be defined by a lambda expression that is compatible with Java's UnaryOperator interface.
