Java ListIterator remove() Method

The remove() method of ListIterator interface is used to remove the last element from the list which is returned by next() or previous() method. The above method can only be called if the add(E) has not been called.

Syntax

Parameters

remove in interface Iterator<E>

Return

Throws:

UnsupportedOperationException– If the given remove operation is not supported by the list iterator.

IllegalStateException– If neither the next() nor the previous() method has been called.

Example 1

  import java.util.ArrayList;  import java.util.ListIterator;  public class JavaListIteratorremoveExample1 {      public static void main(String[] args) {      ArrayList < String > vehicles = new ArrayList < String > ();        vehicles.add(“Car”);      vehicles.add(“Truck”);      vehicles.add(“Bike”);      vehicles.add(“Cycle”);      System.out.println(“The list for the vehicles is given as :”+vehicles);          ListIterator < String > listIterator = vehicles.listIterator();          System.out.println(“Before remove() method is called. : ” + vehicles);          listIterator.next();          listIterator.next();          listIterator.remove();          System.out.println(“After remove() method is called.: ” + vehicles);      }  }  

Test it Now

Output:

The list for the vehicles is given as :[Car, Truck, Bike, Cycle]  Before remove() method is called. : [Car, Truck, Bike, Cycle]  After remove() method is called.: [Car, Bike, Cycle]

Example 2

  import java.util.ArrayList;  import java.util.ListIterator;  public class JavaListIteratorremoveExample2 {       public static void main(String[] args) {       ArrayList < Float > marks = new ArrayList < Float > ();         marks.add(55f);       marks.add(69f);       marks.add(78f);       marks.add(89f);       System.out.println(“The list for the marks is given as :”+marks);           ListIterator < Float > listIterator = marks.listIterator();           System.out.println(“Before remove() method is called. : ” + marks);           listIterator.next();           listIterator.next();           listIterator.remove();           System.out.println(“After remove() method is called.: ” + marks);   }  }  

Test it Now

Output:

The list for the marks is given as :[55.0, 69.0, 78.0, 89.0]  Before remove() method is called. : [55.0, 69.0, 78.0, 89.0]  After remove() method is called.: [55.0, 78.0, 89.0]

Example 3

  import java.util.ArrayList;  import java.util.ListIterator;  public class JavaListIteratorremoveExample3 {     public static void main(String[] args) {     ArrayList < Integer > marks = new ArrayList < Integer > ();           marks.add(25);         marks.add(30);         marks.add(35);         marks.add(40);         marks.add(45);     System.out.println(“The list for the ages is given as :”+marks);          ListIterator < Integer > listIterator = marks.listIterator();          System.out.println(“Before remove() method is called. : ” + marks);          listIterator.next();          listIterator.next();          listIterator.remove();          listIterator.next();         System.out.println(“After remove() method is called.: ” + marks);   }  }  

Test it Now

Output:

The list for the ages is given as :[25, 30, 35, 40, 45]  Before remove() method is called. : [25, 30, 35, 40, 45]  After remove() method is called.: [25, 35, 40, 45]
