Submitted by Ragi Patel on Thu, 11/11/2010 - 15:38

This small Java example shows how to convert ArrayList to array using toArray method of Java ArrayList class.

import java.util.ArrayList;
 
//Java ArrayList to Array using toArray method
public class JavaArrayListToArray {
 
    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 to Array using toArray method.
       
        /*
         * To convert Java ArrayList to Array, use
         * Object[] toArray()
         * method of ArrayList class.
         */
       
        Object[] colors = aListColors.toArray();
       
        //Java ArrayList converted to Array
        for(int i=0; i< colors.length; i++)
            System.out.println(colors[i]);
    }
}
