Answer
It allows clear differentiation between fields and parameters with the same name.
In constructors, parameters often have the same name as class fields. Using 'this' distinguishes the field from the parameter. For example, in a `Product` class with a field `price` and a constructor parameter also named `price`, `this.price = price;` assigns the parameter to the field.
