Object technology is a software engineering approach that emphasizes the use of objects, classes, and interfaces for creating reusable and modular applications. It is based on the principles of abstraction, encapsulation, inheritance, and polymorphism. Object-oriented programming languages like Java and C++ use object technology.

What is object technology? What do you perceive as object technology’s strength? It’s weakness?
Object technology refers to a programming paradigm that uses objects to represent and manipulate data and behavior. Its strength lies in its ability to encapsulate data and behavior within discrete, modular units, promoting code reuse and making it easier to manage complex systems. Its weakness is that it can be more complex and harder to grasp than other programming paradigms, particularly for new developers.
req.getParameter(
)As an AI language model, I do not have access to the request object or any other server-side objects. However, I can provide some information about the `req.getParameter()` method.
`req.getParameter(parameterName)` is a method in Java Servlet technology that retrieves the value of a request parameter with the given name. It returns a string containing the value of the parameter, or null if the parameter does not exist.
Example usage:
```
String username = req.getParameter("username");
String password = req.getParameter("password");
```
In this example, the `getParameter()` method is used to retrieve the values of the "username" and "password" parameters from the HTTP request. These values can then be used to authenticate the user.
