Usage

From source file:MyInterface.java

public static void main(String[] argv) throws Exception {
    MyInterface myintf = (MyInterface) Proxy.newProxyInstance(MyInterface.class.getClassLoader(),
            new Class[] { MyInterface.class }, new ProxyClass(new MyInterfaceImpl()));
    myintf.method();/* w w  w.j av a  2 s  .  co m*/
}

From source file:ProxyTest.java

public static void main(String[] args) {
    Object[] elements = new Object[1000];

    // fill elements with proxies for the integers 1 ... 1000
    for (int i = 0; i < elements.length; i++) {
        Integer value = i + 1;//from   www  . jav a 2  s . c o  m
        InvocationHandler handler = new TraceHandler(value);
        Object proxy = Proxy.newProxyInstance(null, new Class[] { Comparable.class }, handler);
        elements[i] = proxy;
    }

    // construct a random integer
    Integer key = new Random().nextInt(elements.length) + 1;

    // search for the key
    int result = Arrays.binarySearch(elements, key);

    // print match if found
    if (result >= 0)
        System.out.println(elements[result]);
