Java Program to remove an element from List with ListIterator
Let’s say the following is our List with elements −
ArrayList < String > arrList = new ArrayList < String > ();
arrList.add("Jack");
arrList.add("Tom");
arrList.add("Brad");
arrList.add("Amy");
arrList.add("Ben");
arrList.add("Peter");
arrList.add("Katie");
arrList.add("Tim");
Now, use the listIterator(). The next() method returns the next element in the List. Hoverer,remove an element using remove() method −
ListIterator<String>iterator = arrList.listIterator(); iterator.next(); iterator.remove();
Example
import java.util.ArrayList;
import java.util.ListIterator;
public class Demo {
public static void main(String[] args) {
ArrayList<String>arrList = new ArrayList<String>();
arrList.add("Jack");
arrList.add("Tom");
arrList.add("Brad");
arrList.add("Amy");
arrList.add("Ben");
arrList.add("Peter");
arrList.add("Katie");
arrList.add("Tim");
System.out.println("List...");
for (String str: arrList) {
System.out.println(str);
}
ListIterator<String>iterator = arrList.listIterator();
iterator.next();
iterator.remove();
System.out.println("Updated List...");
for (String str: arrList) {
System.out.println(str);
}
}
}
Output
List... Jack Tom Brad Amy Ben Peter Katie Tim Updated List... Tom Brad Amy Ben Peter Katie Tim
