Remove LinkedHashSet elements

We can use remove() method of LinkedHashSet to remove elements from LinkedHashSet collection

boolean remove(Object obj)

Example

  1. import java.util.*;
  2. public class LinkedHashSetRemoveExample {
  3. public static void main(String args[]) {
  4.  
  5. LinkedHashSet lhs = new LinkedHashSet();
  6.  
  7. lhs.add(“java”);
  8. lhs.add(“c”);
  9. lhs.add(“c++”);
  10. System.out.println(“LinkedHashSet before removing elements”);
  11. System.out.println(lhs);
  12. lhs.remove(“java”);
  13. System.out.println(“LinkedHashSet after removing elements”);
  14. System.out.println(lhs);
  15. }
  16. }
import java.util.*;
public class LinkedHashSetRemoveExample {
public static void main(String args[]) {

LinkedHashSet lhs = new LinkedHashSet();

lhs.add(“java”);
lhs.add(“c”);
lhs.add(“c++”);
System.out.println(“LinkedHashSet before removing elements”);
System.out.println(lhs);
lhs.remove(“java”);
System.out.println(“LinkedHashSet after removing elements”);
System.out.println(lhs);
}
}


Removing all elements at once

We can use clear() method of LinkedHashSet to remove all elements in one go

  1. import java.util.*;
  2. public class LinkedHashSetRemoveAllExample {
  3. public static void main(String args[]) {
  4.  
  5. LinkedHashSet lhs = new LinkedHashSet();
  6.  
  7. lhs.add(“java”);
  8. lhs.add(“c”);
  9. lhs.add(“c++”);
  10. System.out.println(“LinkedHashSet before removing all elements”);
  11. System.out.println(lhs);
  12. lhs.clear();
  13. System.out.println(“LinkedHashSet after removing all elements”);
  14. System.out.println(lhs);
  15. }
  16. }
import java.util.*;
public class LinkedHashSetRemoveAllExample {
public static void main(String args[]) {

LinkedHashSet lhs = new LinkedHashSet();

lhs.add(“java”);
lhs.add(“c”);
lhs.add(“c++”);
System.out.println(“LinkedHashSet before removing all elements”);
System.out.println(lhs);
lhs.clear();
System.out.println(“LinkedHashSet after removing all elements”);
System.out.println(lhs);
}
}
