What are constructors in C++ and Java?

What are constructors in C++ and Java?

Constructors are special class functions in C++ and Java that are called when an object is created. They initialize the object.

Can you explain the difference between default and parameterized constructors?

Sure! A default constructor has no parameters, while a parameterized constructor takes arguments to initialize an object with specific values.

How do you define a constructor in C++?

In C++, you define a constructor by creating a function with the same name as the class and no return type. For example:

class MyClass {
public:
    MyClass() {
        // initialization code
    }
};

Is there a concept of constructor overloading in Java?

Yes, Java supports constructor overloading, allowing you to have multiple constructors with different parameters in the same class.
