What are the different ways to use Java proxies?

There are several ways to set up Java proxies.

1. Static proxy: A proxy class directly references the object being proxied, enabling the proxy class to call and control the methods of the proxied class.
2. Dynamic proxy: Using Java’s reflection mechanism, a proxy class is dynamically generated at runtime, implementing the interface of the class being proxied and invoking its methods within its own methods.
3. CGLIB proxy: Using byte code technology, a subclass of the class being proxied is generated at runtime and the methods of the class being proxied are overridden, allowing for the class to be proxied.
4. Dynamic proxy in JDK: Using a proxy class that implements the InvocationHandler interface to implement the invoke method to proxy methods of the class being represented, dynamic proxy can only represent classes that implement interfaces.
