Usage

From source file:MainClass.java

public static void main(String[] a) {
    String elements[] = { "A", "B", "C", "D", "E" };
    Set set = new HashSet(Arrays.asList(elements));

    elements = new String[] { "B", "D", "F", "G", "1", "2", "3", "4" };
    Set set2 = new HashSet(Arrays.asList(elements));

    set.removeAll(set2);/*  ww  w.  j av a  2s  .c  om*/
    System.out.println(set);
