Java LinkedList forEach() Method
Example
Use a lambda expression in the LinkedList's forEach() method to print every item in the 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(1);
numbers.forEach( (n) -> { System.out.println(n); } );
}
}
Definition and Usage
The forEach() method performs an action on every item in a list. The action can be defined by a lambda expression that is compatible with the accept() method of Java's Consumer interface.
