Remove all elements from Java LinkedHashSet
To remove all the elements from LinkedHashSet in Java, use the clear() method.
The following is an example to declare LinkedHashSet and add elements to it −
LinkedHashSet<Integer> hashSet = new LinkedHashSet<Integer>(); hashSet.add(10); hashSet.add(20); hashSet.add(30); hashSet.add(40); hashSet.add(50); hashSet.add(60);
Use the clear() method to remove all elements −
hashSet.clear();
The following is an example −
Example
import java.util.LinkedHashSet; public class Demo { public static void main(String[] args) { LinkedHashSet<Integer> hashSet = new LinkedHashSet<Integer>(); hashSet.add(10); hashSet.add(20); hashSet.add(30); hashSet.add(40); hashSet.add(50); hashSet.add(60); System.out.println("LinkedHashSet..."); System.out.println(hashSet); // cleared the set hashSet.clear(); System.out.println("
Updated LinkedHashSet..."); System.out.println(hashSet); } }
Output
LinkedHashSet... [10, 20, 30, 40, 50, 60] Updated LinkedHashSet... []
