Constructors initialize new objects, setting initial states for fields.
In Java, a constructor is a special block of code called when an object is instantiated. Its purpose is to initialize the object's fields with default or specific values, ensuring that the object starts in a valid state. For example, in an e-commerce application, a Product class might have a constructor to set the initial price and stock level when a new product is created. Without proper initialization, objects might be in an inconsistent or unusable state.
