Write a class called RationNumber that represents a fraction with an integer num

Question

Write a class called RationNumber that represents a fraction with an integer numerator and denominator. A RationalNumber object should have the following methods:

public RationalNumber(int numerator, int denominator)

Constructs a new rational number to represent the ratio (numerator/denominator). The denominator cannot be 0.

so throw an IllegalArgumentException if 0 is passed.

public RationalNumber ()

Constructs a new rational number to represent the ratio (0/1).

public int getDenominator()

Returns this rational number's denominator value; for example, if the ratio is (3/5), returns 5.

public int getNumerator()

Returns this rational number's numerators value; for example, if the ratio is (3/5), returns 3.

public String toString()

Returns a String representation of this rational number, such as "3/5". You may wish to omit denominators of 1.

returning "4" instead of "4/1".

An extra challenge would be to maintain your RationalNumber objects in reduced form, avoiding rational numbers such as 3/6 in favor of 1/2, or avoiding 2/-3. Another possible extra feature would be methods to add, subtract, multiply, and divide two rational numbers.

import java.util.*;

public class RationalNumber{

public int numerator

public int denominator

public int x

public int y

}

public RationalNumber(int numerator, int denominator)

// returns the greatest common divisor of x and y

private int gcd(int x, int y) {

while (y != 0) {

int temp = x % y;

x = y;

y = temp;

        }

        return x;

public int getNumerator();

return = new Numerator

public int getDenominator();

return = new Denominator

public String toString();
