Question

Answer the following in brief. Give a program code example wherever applicable.

Constructors cannot be called. Then when do they get executed?

Answer 1

A constructor is executed automatically when an object of the class is created using the new keyword. It is used to initialize the object. When the object s is created using new Student(), the constructor is automatically invoked.

class Student
{
    Student() 
    {
        System.out.println("Constructor executed");
    }

    public static void main(String[]args) 
    {
        Student s = new Student();
    }
}
