Add dividemethod to take another Fraction as the parameter and return a new Fraction that is the division of current Fraction and the Fraction in the parameter. (public Fraction divide(Fraction f)).-Add scaleup and scaledownmethods to the Fraction class. The scaleupmethod will take afactor as the parameter and multiply the numerator by the factor. The scaledownmethodwill take a factor as the parameter and multiply the denominator by the factor. -Add a scalemethod which will have two parameters: factorand flag. The flagis boolean. Ifflagis true, then scale up the fraction; otherwise scale down the fraction. -Both scaledownand scalemethods must check if the factor is 0. If it is 0, a warningmessage is printed out and no scaling is operated.-Add two more constructors. One of the constructors will have no parameters; it initializesthe fraction to 0/1. The other constructor will have one parameter, representing thenumerator of the fraction; the denominator of the fraction will be 1. -Write a program named FractionScalethat prompts the user of a fraction and a scalefactor. Here is what the user will see on the screen: This program performs the scaling operations on a fraction. Enter a fraction:3/7Scale up or down (1: up, 0: down):1Enter a scale factor:2Scaled fraction is: 6/7You can assume that the user always enters two integers separated by a slash (/) for thefaction. However, the user may enter any number of spaces before and after each integer.
