Question

java code

Write a class called FractionObject that represents a fraction with an integer numerator and denominator as fields. A Fraction Object object should have the following methods: A constructor with int numerator, int denominator as parameters - Constructs a new fraction object to represent the ratio (numerator/denominator). The denominator cannot be 0, so output a message if O is passed and set the numerator and denominator to 1. A constructor with no parameters - Constructs a new FractionObject to represent the ratio (0/1). getDenominator() - Returns this FractionObject's denominator value; for example, if the ratio is (3/5), returns 5. getNumerator() - Returns this Fraction Object's numerator value; for example, if the ratio is (3/5), returns 3. getDecimal() - Returns this Fraction Object's decimal value Demonstrate the class in a program that creates a Fraction Object. Use the following data test your program: numerator = 5, and denominator = 2 • numerator = 3, and denominator = 0 numerator = 1, and denominator = 6

Answer 1

please drop a comment if there's an issue. the code is divided into two class- 1) FractionObject (the required class), 2) Main (the class that demonstrates )

//-------------------------------------------------------

The numberator of fl is5 Denominator cannot be 0 The denominator of f2 isi the decimal value of f3 is 0.16666667

//------------------------------------------------------

public class Main {

    public static void main(String[] args) {

        // creates an object with numberator=5, and denominater=2

        FractionObject f1 = new FractionObject(5, 2);

        System.out.println("The numberator of f1 is" + f1.getNumerator());

        // creates an object with numberator=3, and denominater=0

        FractionObject f2 = new FractionObject(3, 0);

        System.out.println("The denominator of f2 is" + f2.getDenominator());

        // creates an object with numberator=1, and denominater=6

        FractionObject f3 = new FractionObject(1, 6);

        System.out.println("the decimal value of f3 is " + f3.getDecimal());

    }

}

// the required class

class FractionObject {

    // member variables

    int numerator;

    int denominator;

    // the required constructor that takes 2 parameters

    FractionObject(int numerator, int denominator) {

        // checks if denominator==0

        if (denominator == 0) {

            System.out.println("Denominator cannot be 0");

            // sets the values to 1

            this.numerator = 1;

            this.denominator = 1;

        } else {

            this.numerator = numerator;

            this.denominator = denominator;

        }

    }

    FractionObject() {

        this.numerator = 1;

        this.denominator = 0;

    }

    int getNumerator() {

        return numerator;

    }

    int getDenominator() {

        return denominator;

    }

    // returns the decimal value of the fraction

    float getDecimal() {

        // calcultes the decimal value

        float decimal = this.numerator / (float) this.denominator;

        return decimal;

    }

}
