Chapter: Data Structures Last Updated: 21-07-2016 10:29:11 UTC

Program:

            /* ............... START ............... */
                
import java.util.ArrayList;

public class JavaArrayListToArray {
	public static void main(String a[]) {
		ArrayList<String> arrayList = new ArrayList<String>();
		arrayList.add("Java");
		arrayList.add("Scan");

		System.out.println("Actual ArrayList:" + arrayList);
		String[] strArr = new String[arrayList.size()];
		arrayList.toArray(strArr);
		System.out.println("Created Array content:");
		for (String str : strArr) {
			System.out.println(str);
		}
	}
}
                /* ............... END ............... */
        

Output

Actual ArrayList:[Java, Scan]
Created Array content:
Java
Scan

Notes:

  • The java.util.ArrayList.toArray(arry[]) method returns an array containing all of the elements in this list in proper sequence (from first to last element).
