Usage

From source file:MainClass.java

public static void main(String[] a) {
    List l1 = Arrays.asList(new String[] { "A", "B", "C" });
    List l2 = Arrays.asList(new String[] { "A", "C", "D" });
    Collections.copy(l1, l2); // works
    Collections.copy(l2, l1); //
    System.out.println(l1);/*from  w ww. jav a  2  s.c  om*/
    System.out.println(l2);
}
