Usage

From source file:MainClass.java

public static void main(String args[]) {
    Vector vector = new Vector();
    vector.addElement(new Integer(5));
    vector.addElement(new Float(-14.14f));

    System.out.println(vector);/*from  w  w  w .  ja  v a 2 s  .  co m*/

    String s = new String("String to be inserted");
    vector.insertElementAt(s, 1);
    System.out.println(vector);

    vector.removeElementAt(2);
    System.out.println(vector);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Constructor con = Point.class.getConstructor(new Class[] { int.class, int.class });
    Point obj = (Point) con.newInstance(new Object[] { new Integer(1), new Integer(1) });
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
