Declaring a constructor in Java requires defining it with the same name as the class it belongs to, which is a key characteristic that distinguishes constructors from other methods. Furthermore, constructors do not have a return type, not even 'void'. This is crucial because when objects are instantiated, the constructor initializes the object's properties without returning any value.

By following this pattern, Java ensures that the object is initialized properly when it's created. For example, if you have a class called `Car`, the constructor for this class must also be named `Car` and will look something like this:

```java

public class Car {

public Car() {

// Constructor code here

}

}

```

This structure highlights that the constructor serves a special purpose and acts differently from conventional methods in the class, which typically have their own return types and can share names with other methods as long as their parameters vary (method overloading).

The requirement of the constructor's naming convention and that it has no return type not only serves a functional purpose but also enhances the readability and maintainability of the code, as it clearly indicates which method is responsible for initializing an instance of the class.
