A constructor in Java is a special method that is used to initialize an object. It is called when an object of a class is created. It is a block of code that is called when an instance of an object is created, and memory is allocated for the object. It always has the same name as the class and does not have a return type (not even void). |

A constructor in programming is like a special method used to create and set up a new object. Think of it like a recipe that tells you how to make a dish. When you decide to cook something, you follow a recipe that tells you what ingredients to use and how to mix them. Similarly, a constructor in programming tells the computer what it needs to do to create a new object of a certain class. When you create a new object, the constructor sets up everything that object needs to start its life. This might include setting initial values for certain properties of the object. For example, if you have a class for a "Car," the constructor might set up the car's color, model, and make when you create a new car object. In summary, a constructor is like a recipe or a set of instructions for creating a new object in a program. It helps initialize the object with default values and gets it ready for use. |
