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?

Assertion (A): Static method can access static and instance variables.

Reason (R): Static variable can be accessed only by static method.

1. Assertion and Reason both are correct.
2. Assertion is true and Reason is false.
3. Assertion is false and Reason is true.
4. Assertion and Reason both are false.
