Write a client program that allows the user to add up any number of non-zero fractions. The program should display the running total as an exact fraction (in simplified form as numerator / denominator), and as an approximate double value. The user can finish by entering a fraction that represents a zero fraction import java.util.ArrayList; import java.util.Scanner; //Define the class Fraction class Fraction { private int n, d; public Fraction() { //Initialize the values this.n = this.d = 0; } public Fraction(int n, int d) { //Initialize the variables this.n = n; this.d = d; } //Define the getter function getNum() that returns the numerator public int getNum() { //Returns numerator return n; } //Define the getter function getDen() that returns the denominator public int getDen() { //Returns denominator return d; } //Define the boolean function isZero() that returns 0 if numerator is 0 and denominator is not equals to zero public boolean isZero() { return(getNum() == 0 && getDen() != 0); } public boolean isequals(Object c) { Fraction f = (Fraction) c; return(Integer.compare(n,f.n))==0 && (Integer.compare(d,f.d)==0); } //Define the function getSimplifiedFraction() that returns the simplified fraction public String getSimplifiedFraction() { //Decalre the string variable result to store the result String result = ""; //if the numerator and denominator both are zero if(getNum() == 0 && getDen() == 0) //result is zero result = "0"; //if the numerator is zero and denominator is non-zero else if(isZero()) //result is zero result = "0"; //if the numerator is non-zero and denominator is zero else if(getNum() != 0 && getDen() == 0) //result is Undefined result = "Undefined"; //for a defined and non-zero fraction else { //if the remainder is zero if(getNum() % getDen() == 0) result = (getNum() / getDen()) + ""; //if the numerator and denominator both are greater than zero else if(getNum() < 0 && getDen() < 0) result = (getNum() * -1) + "/" + (getDen() * -1); //if any of them is zero else if(getNum() < 0 || getDen() < 0) { //if the numerator is greater than zero if(getNum() < 0) result = "-" + (getNum() * -1) + "/" + getDen(); // appending a sign. //if the denominator is zero else result = "-" + getNum() + "/" + (getDen() * -1); // appending a sign. } //both are non-zero else result = (getNum() + "/" + getDen()); } //return the result return result; } //Define the method display() that displays the resultant fraction public void display() { //Call and display the fraction System.out.println(getSimplifiedFraction()); } public Fraction add(Fraction rhs) { Fraction sum = new Fraction(); sum.d = d * rhs.d; sum.n = n * rhs.d + d * rhs.n; sum.simplify(); return sum; } private void simplify() { int a,b; if(Math.abs(n) > Math.abs(d)) { a = Math.abs(n); b = Math.abs(d); } else { a = Math.abs(d); b = Math.abs(n); } int r = a%b; while(r != 0) { a = b; b = r; r = a%b; } //divide numerator and denominator by b n /= b; d /= b; } } //Define the class TestFraction class TestFraction { //Define the main method public static void main(String[] args) { //Declare the variables to store the numerator and denominator String res; int num, den, num1, den1; //Declare an ArrayList to store the results ArrayList fractions = new ArrayList<>(); //Create the object for scanner class Scanner sc = new Scanner(System.in); //use the do-while loop to iterate test the conditions do { //Prompts the user to enter the numerator System.out.print("Enter the num: "); //Store the Integer part only num = Integer.parseInt(sc.nextLine().trim()); //If the numerator is less than zero if(num < 0) //Break from loop break; //Prompts the user to enter the denominator System.out.print("Enter the den: "); //store the integer part only den = Integer.parseInt(sc.nextLine().trim()); //Create the object of Fraction class Fraction fraction = new Fraction(num, den); System.out.print("Enter the num to compare: "); num1 = Integer.parseInt(sc.nextLine().trim()); if(num1 < 0) break; System.out.print("Enter the den to compare: "); den1 = Integer.parseInt(sc.nextLine().trim()); Fraction fraction1 = new Fraction(num1, den1); if(fraction1.isequals(fraction)) { System.out.println("\nTrue-> Second fraction is equal to First Fraction"); } else System.out.println("\nFalse-> Second fraction is not equal to First Fraction"); // if isequal() returns zero. //Add the resultant fractions into the ArrayList fractions.add(fraction); //Display the resultant fraction res = fraction.getSimplifiedFraction(); System.out.println("Fraction added to list as: " + res + "\n"); //result is stored in ‘res’ variable }while(res != "0"); //Display all fractions that are stored in the ArrayList System.out.println("\nDISPLAYING ALL FRACTIONS:\n" + "-------------------------"); //Use the loop to display the values stored in the ArrayList for(Fraction fr : fractions) fr.display(); //to print the new line System.out.println(); sc.close(); Fraction f = new Fraction(4, 8); System.out.println("1st fraction: "); f.display(); Fraction fc = new Fraction(8, 24); System.out.println("2nd fraction: "); fc.display(); Fraction res1 = f.add(fc); System.out.println("Sum: "); res1.display(); } }
