Submitted by Ragi Patel on Thu, 11/11/2010 - 15:29

This small Java Example shows how to remove element from ArrayList object.

//Java ArrayList Remove
 
import java.util.ArrayList;
 
public class JavaArrayListRemove {
    public static void main(String args[]){
       
        //create new ArrayList
        ArrayList<String> aListColors = new ArrayList<String>();
        aListColors.add("Red");
        aListColors.add("Green");
        aListColors.add("Blue");
       
        //Java ArrayList Remove
       
        /*
         * To remove single element from ArrayList, use
         * Object remove(int index) method.
         *
         * This method returns object that has been removed from
         * ArrayList object.
         */
       
        //this will remove green from ArrayList
        aListColors.remove(1);
       
        /*
         * OR
         * remove the element from ArrayList by passing the element itself
         * instead of index using
         * Object remove(Object object) method.
         */
       
        //this will remove Blue from ArrayList
        aListColors.remove("Blue");
       
        System.out.println(aListColors);
    }
}
