Remove all items from ArrayList in Java

This code deletes all objects from the ArrayList in java. To flush ArrayList, you need to use the method of the ArrayList  clear():

import java.util.ArrayList; 
public class Clear{ 
 public static void main(String[] args) {
 // Create an ArrayList
 ArrayList arraylist = new ArrayList(); 
 
 //add the elements to ArrayList
 arraylist.add("E1"); 
 arraylist.add("E2"); 
 arraylist.add("E3"); 
 arraylist.add("E4"); 
 
 // show list before deletion
 System.out.println("Before: "+ arraylist); 
 
 arraylist.clear(); 
 
 // show list after deletion
 System.out.println("After: "+ arraylist); 
 }
}

Output:

Before: [e2, e1, e4, e3]
after: []
