Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array.

Usage

From source file:Main.java

public static void main(String[] args) {

    LinkedList<String> theList = new LinkedList<String>();
    theList.add("A");
    theList.add("B");
    theList.add("C");
    theList.add("D");

    String[] my = theList.toArray(new String[0]);

    for (int i = 0; i < my.length; i++) {
        System.out.println(my[i]);
    }/*from w w  w.  j  a  va  2 s.  c  o m*/
}

From source file:Main.java

public static void main(String[] args) {

    LinkedList<String> list = new LinkedList<String>();

    // add some elements
    list.add("Hello");
    list.add("from java2s.com");
    list.add("java tutorial");

    System.out.println(list);/*from w w w.  jav  a 2  s .c o  m*/

    // create an array and copy the list to it
    Object[] array = list.toArray(new Object[4]);

    System.out.println(Arrays.toString(array));
