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:MainClass.java

public static void main(String args[]) {
    String[] a = new String[] { "a", "c", "b" };

    List l = (Arrays.asList());
    String stuff[] = (String[]) l.toArray(new String[0]);
}

From source file:Main.java

public static void main(String[] argv) {
    JTextPane textPane = new JTextPane();

    List list = new ArrayList();

    TabStop[] tstops = (TabStop[]) list.toArray(new TabStop[0]);
    TabSet tabs = new TabSet(tstops);

    Style style = textPane.getLogicalStyle();
    StyleConstants.setTabSet(style, tabs);
    textPane.setLogicalStyle(style);/*from w  ww  . ja  va2  s  .  c om*/
}
