Answer
'this' helps differentiate instance fields from parameters.
In Java, it's common to have constructor parameters with the same names as class fields, especially in simple data models like a Product in e-commerce. Using 'this' clarifies that a field is being referenced, not a parameter. This prevents bugs and ensures that the field is correctly initialized.
