Add a private method simplify() to Fraction class that converts a fraction to its simplest form. For example, the fraction 20 / 60 should be stored in the class instance variables as 1 / 3 (i.e. numerator = 1, denominator = 3). you will need a method to determine the Greatest Common Divisor (GCD. both of these methods (simplify and gcd) must be private. As these methods are private, client programs cannot access them. They can only be accessed within the Fraction class. Given their purpose, it would mean that any Fraction class method that modifies the instance variables (e.g.: input, add, constructor, set) should call the simplify() method to reduce the instance variables to their minimum values. Thus, these methods are used only for housekeeping; they are not to be used by client programs. 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; }
