Add a toString() method to Fraction class that returns the fraction as a String in the form "x / y", where x and y are numerator and denominator respectively. As the method does not do any display itself, the output can be done by a client program that calls the method in an output statement. Use client program to test this functionality; i.e. provide an output statement to display a fraction as its String representation. class Fraction2 { private int n, d; public Fraction() { this.n = this.d = 0; //Initialize the values } public Fraction(int n, int d) { this.n = n; //Initialize the variables 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; }
