Remove Specific Elements From LinkedList In Java

Chapter: Data Structures Last Updated: 28-08-2016 19:28:35 UTC

Program:

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

public class JavaRemoveSpecificElement {
	public static void main(String[] args) {

		// Create a LinkedList
		LinkedList<String> linkedlist = new LinkedList<String>();

		// Add elements to LinkedList
		linkedlist.add("Item1");
		linkedlist.add("Item2");
		linkedlist.add("Item3");
		linkedlist.add("Item4");
		linkedlist.add("Item5");

		// Displaying Elements before remove
		System.out.println("Before Remove:");
		for (String str : linkedlist) {
			System.out.println(str);
		}

		// Removing "Item4" from the list
		linkedlist.remove("Item4");

		System.out.println("\nAfter Remove:");
		for (String str2 : linkedlist) {
			System.out.println(str2);
		}
	}
}

                /* ............... END ............... */
        

Output

Before Remove:
Item1
Item2
Item3
Item4
Item5

After Remove:
Item1
Item2
Item3
Item5

Notes:

  • remove(Object o) method to perform this remove.
  • public boolean remove(Object o): Removes the first occurrence of the specified element from this list, if it is present. If this list does not contain the element, it is unchanged. Returns true if this list contained the specified element (or equivalently, if this list changed as a result of the call).
