Remove an element from an ArrayList using the ListIterator in Java
An element can be removed from an ArrayList using the ListIterator method remove(). This method removes the current element in the ArrayList. If the remove() method is not preceded by the next() method, then the exception IllegalStateException is thrown.
A program that demonstrates this is given as follows.
Example
import java.util.ArrayList;
import java.util.ListIterator;
public class Demo {
public static void main(String[] args) {
ArrayList<String> aList = new ArrayList<String>();
aList.add("Apple");
aList.add("Mango");
aList.add("Guava");
aList.add("Orange");
aList.add("Peach");
System.out.println("The ArrayList elements are: ");
for (String s: aList) {
System.out.println(s);
}
ListIterator li = aList.listIterator();
li.next();
li.remove();
System.out.println("
The element Apple is removed");
System.out.println("
The ArrayList elements are: ");
for (String s: aList) {
System.out.println(s);
}
}
}Output
The output of the above program is as follows −
The ArrayList elements are: Apple Mango Guava Orange Peach The element Apple is removed The ArrayList elements are: Mango Guava Orange Peach
