How to Make a Proxy in Java

Instructions

1

Create a generic interface that contains an abstract method. For example:

interface ProxyInterface
public void method();


2

Create two classes that implement the ProxyInterface:

class P1 implements ProxyInterface


class P2 implements ProxyInterface


3

Create an implementation of "method()" in class "P2." Then, call the P2 version of "method()" from "P1." P1 now represents the proxy class:

class P1 implements ProxyInterface

P2 p = new P2();

public void method()
p.method();


class P2 implements ProxyInterface

public void method()
System.out.println("Hi");
