Assertion (A): An argument is a value that is passed to a method when it is called.

Reason (R): Variables which are declared in a method prototype to receive values are called actual parameters

1. Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A)
2. Both Assertion (A) and Reason (R) are true and Reason (R) is not a correct explanation of Assertion(A)
3. Assertion (A) is true and Reason (R) is false
4. Assertion (A) is false and Reason (R) is true

Invoking a method by passing the objects of a class is termed as:

1. Call by reference
2. Call by value
3. Call by method
4. Call by constructor

Method which reverses a given number is:

1. Impure method
2. Pure method
3. Constructor
4. Destructor

Consider the following program segment and answer the questions below:

class calculate

{
  int a; double b; 
  calculate()

  {

  a=0; 
  b=0.0;

  }

  calculate(int x, double y)

  {

  a=x;
  b=y;

  }

void sum()

{

  System.out.println(a*b);

}}

Name the type of constructors used in the above program segment?
