Chapter: Data Structures Last Updated: 05-09-2016 16:24:01 UTC

Program:

            /* ............... START ............... */
                
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

public class JavaAppendAllElementOfListToLinkedList {

	public static void main(String[] args) {

		// create a LinkedList
		LinkedList<String> list = new LinkedList<String>();

		// Add elements to the LinkedList
		list.add("Java");
		list.add("Pascal");
		list.add("Cobol");
		list.add("C");

		// Displaying linked list before add
		System.out.println("Before: LinkedList: " + list);

		// create a new list having few elements
		List<String> arrayList = new ArrayList<String>();
		arrayList.add("Item1");
		arrayList.add("Item2");
		arrayList.add("Item3");

		// Append the list elements to LinkedList
		list.addAll(arrayList);

		// Displaying the LinkedList after addAll
		System.out.println("After: LinkedList: " + list);
	}
}
                /* ............... END ............... */
        

Output

Before: LinkedList: [Java, Pascal, Cobol, C]
After: LinkedList: [Java, Pascal, Cobol, C, Item1, Item2, Item3]

Notes:

  • public boolean addAll(Collection<? extends E> c): Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection’s iterator.
