Java Program to add and remove elements from a set which maintains the insertion order
Create a LinkedHashSet −
LinkedHashSet<Integer>set = new LinkedHashSet<Integer>();
Now, add elements to the Set −
set.add(20); set.add(60); set.add(80); set.add(120); set.add(150); set.add(200);
For removing the elements −
set.remove(150); set.remove(260);
Above process of insertion and deletion won’t affect the insertion order.
Example
import java.util.LinkedHashSet;
public class Demo {
public static void main(String[] args) {
LinkedHashSet<Integer>set = new LinkedHashSet<Integer>();
set.add(20);
set.add(60);
set.add(80);
set.add(120);
set.add(150);
set.add(200);
set.add(220);
set.add(260);
set.add(380);
System.out.println("Set = "+set);
set.remove(150);
set.remove(260);
System.out.println("Updated Set = "+set);
set.remove(60);
System.out.println("Updated Set = "+set);
}
}Output
Set = [20, 60, 80, 120, 150, 200, 220, 260, 380] Updated Set = [20, 60, 80, 120, 200, 220, 380] Updated Set = [20, 80, 120, 200, 220, 380]
