In programming, a constructor is a special type of method that is used to initialize an object when it is created. It’s called a constructor because it “constructs” or sets up the object.
The purpose of a constructor is to ensure that an object is initialized properly and has valid initial values for its member variables or properties. A constructor typically takes parameters that are used to initialize the object’s state, and it can also perform additional setup tasks if necessary.
Constructors are a key concept in object-oriented programming, and they are used to create objects of a particular class. They are called automatically when an object is created, and they can be used to perform any necessary initialization or setup tasks before the object is used.
In summary, the purpose of a constructor in programming is to ensure that an object is properly initialized and has valid initial values for its properties.
