How to make ArrayList elements to an Array?
Here simply use toArray method. toArray method return an Array.First of all declare a ArrayList type of String. Add five string type elements. Declare an String Array which length is equal to ArrayList size.
package com.tech.mindclues; import java.util.ArrayList; public class ArrayListConvertToArray { public static void main(String args[]) { ArrayListlistToArray = new ArrayList (); listToArray.add("Mind"); listToArray.add("Clues"); listToArray.add("Hunt"); listToArray.add("Hagrid"); listToArray.add("Tom"); //declare a array which length is equal to arraylist size. String[] ary = new String[listToArray.size()]; ary = listToArray.toArray(ary);//Using toArray method to set the ArrayList to Array System.out.println("Array elemens :"); for (int i = 0; i < ary.length; i++) { System.out.println(ary[i]); } } }
