Java Collection, LinkedList Exercises: Iterate through all elements in a linked list

Java Collection, LinkedList Exercises: Exercise-2 with Solution

Write a Java program to iterate through all elements in a linked list.

Sample Solution:-

Java Code:

import java.util.LinkedList;
  public class Exercise2 {
  public static void main(String[] args) {
    // create an empty linked list
     LinkedList<String> l_list = new LinkedList<String>();
   // use add() method to add values in the linked list
          l_list.add("Red");
          l_list.add("Green");
          l_list.add("Black");
          l_list.add("White");
          l_list.add("Pink");
         // Print the linked list
  for (String element : l_list) {
    System.out.println(element);
    }
 }
}

Sample Output:

Red                                                                    
Green                                                                  
Black                                                                  
White

getEnumMap

Converts to enum to Map where key is the name and value is Enum itself. 

public static <E extends Enum<E>> Map<String, E> getEnumMap(final Class<E> enumClass) {
    return Arrays.stream(enumClass.getEnumConstants())
            .collect(Collectors.toMap(Enum::name, Function.identity()));
}
