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

Method prototype for the method compute which accepts two integer arguments and returns true/false.

1. void compute (int a, int b)
2. boolean compute (int a, int b)
3. Boolean compute (int a,b)
4. int compute (int a, int b)

Define a class to overload the method display() as follows:

void display(): To print the following format using nested loop.

1 2 1 2 1
1 2 1 2 1
1 2 1 2 1

void display (int n, int m) : To print the quotient of the division of m and n if m is greater than n otherwise print the sum of twice n and thrice m.

double display (double a, double b, double c) — to print the value of z where

$z = p \times q$

$p = \dfrac{a + b}{c}$

$q = a + b + c$

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?
