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[]) {
ArrayList listToArray = 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]);
}
}
}
