Answer:
Subroutine or called function.
Explanation:
Procedural programming is a programming techniques of creating modular divisions between lines of code, with a provision to call and run a block of code at any given instance in the program.
A program flow control breaks at will from the main function to a target defined function or subroutine, which returns a value back to the normal flow of the program. It uses conditional and loop statement to achieve its task.
Answer: Constructors can specify parameters but not return types.
Explanation:
public class Student {
int roll_no;
public Student(int a) {
roll_no = a;
}
public static void main(String[] args) {
Student abs = new Student(10);
System.out.println(abc.roll_no);
}
}
In the above code we have illustrated the working of constructors. We have a class with the name Student. then a constructor is created of the class called as the class constructor. In the main we create an object of the class and with this object we invoke the constructor and also pass a parameter. Here in the code we are passing the roll no of the student.
So we can say that constructor is called during the runtime when the object created invokes the constructor so a constructor can have many arguments but it does not have a return type.
