Question

Design a class named Fraction. This class is used to represent a ratio of two integers, such as 6 / 9. Include accessors and mutators that allow the user to get and set the numerator and the denominator. Also include a member method that returns the value of the numerator divided by the denominator as double (for example, 0.666…). Include an additional member method that returns the value of the fraction reduced to lowest terms as string. For example, instead of returning 6 / 9, the function should return 2 / 3 as a string. This will require finding the greatest common divisor for the numerator and the denominator, and then dividing both by that number. Include a private method that returns the greatest common divisor of two integers. Write a test program that tests several examples of fractions and displays the results. java is programming language,

Fraction.java

package c14;

public class Fraction {
   private int numerator;
   private int denominator;
   Fraction(int num,int den){
       numerator = num;
       denominator = den;
   }

   public void showFractionForm(){
       int partA = numerator/denominator;
       int partB = numerator%denominator;
       if(partA!=0){
           System.out.println(partA+"("+partB+"/"+denominator+")");
       }else{
           System.out.println(partB+"/"+denominator);
       }
   }

   public void determineLowestTerm(){
       int gcd=0;

       if(numerator==0){
           denominator = 1;
           System.out.println(numerator+"/"+denominator);
           return;
       }
       for (int i = 1; i <= numerator; i ++)
       {
           if (numerator%i == 0 && denominator%i == 0)
           {
               gcd = i;
           }
       }

       numerator = numerator / gcd;
       denominator = denominator / gcd;
       System.out.println(numerator+"/"+denominator);
   }

   public void determineDecimalEquivalent(){
       double value = numerator*1.0/denominator;
       System.out.println(value);
   }
  

   public static void main(String[] args) {
       Fraction f1 = new Fraction(6, 9);
       System.out.println("Fraction(6, 9).....\n");
       System.out.println("Fraction form is ");
       f1.showFractionForm();
       System.out.println("\nLowest term is ");
       f1.determineLowestTerm();
       System.out.println("\nDecimal equivalent is ");
       f1.determineDecimalEquivalent();
   }

}

- Console x ** Ek <terminated> Fraction (3) [Java Application] C:\P Fraction (6, 9).... ominator) Fraction form is 6/9 is 0) Lowest term 2/3 Decimal equivalent is 0.6666666666666666
