How can i make this OOP Program?

Question

Declare a class test in which you declare two members of int type a, b and declare a method named divide and divide two members and throw exception of divided by zero

Answer 1

/* C++ */

using namespace std;

#include <iostream>

class Test

{

private:

int A;

int B;

public:

Test ( int a, int b)

{

A=a; B=b;

}

double Divide()

{

double dblReturn;

if (B==0)

{

dblReturn = 0;

throw (" Divide by Zero exception");

}

else

{

dblReturn = (double)(A*1.0f)/B;

}

return(dblReturn);

}//Divide

};

int main()

{

int a,b;

a=b=1;

while (!((a==0) && (b==0)) )

{

std::cout << "Input the numerator and denominator separated by a space : zeros to quit :> ";

std::cin >> a >> b;

Test * myTest;

myTest = new Test(a,b);

try

{

std::cout << "Quotient is " << myTest->Divide() << endl;

}

catch (char * str)

{

std:cerr << str << endl;

}

delete(myTest);

} //while

}

//************* Java *****************//

import java.io.*;

class TestException

{

private double A;

private double B;

public TestException( double a, double b)

{

A=a; B=b;

}

public double Divide() throws ArithmeticException

{

double dblReturn;

if (B==0)

{

dblReturn=0;

throw(new ArithmeticException("Divide by zero"));

}

else

{

dblReturn = ( (double) (A*1.0f)/B);

}

return(dblReturn);

}

public static void main(String args[])

{

double a,b;

a=b=1;

Console console = System.console();

while (! ((a==0) && (b==0)))

{

System.out.print(" Input numerator : zero to quit :>");

String inbuff = console.readLine();

a = Double.parseDouble(inbuff);

System.out.print(" Input denominator : zero to quit :>");

inbuff = console.readLine();

b = Double.parseDouble(inbuff);

TestException myTest = new TestException(a,b);

try

{

double dblResult = myTest.Divide();

System.out.println(" Quotient is " + dblResult);

}

catch (ArithmeticException ex) { System.out.println(" Division by zero "); }

} //while

} //main

} //class
