Complete this in Java language • Define instance variables for the class.• Define a constructor to initialize those variables.• Define one or more mutators to modify the variables.• Define one or more accessors to retrieve information about objects created from the class.• Document the class, the constructor and each of the methods.There is no printing and you will not need Scanners, or do any input.You have 45 minutes to complete the problems. You may not access any notes (other than the Java Quick Reference), files,or communicate with anyone in any way (other than the instructor).Problem StatementDefining ClassesWrite and document the definition for the Fraction class. The Fraction class represents a rational number in the form of anumerator and denominator.FractionClassO Fieldsdenominator : intnumerator : intE Methods* Fraction(int num, int denam)* getvalue): double* setDenominator[int denam): void* setNumerator(int num) : void* tostring0: String• Each Fraction object has two int instance variables: numerator and denominator.• The class has one constructor that takes two int parameters in the order numerator, denominator.• The class has one accessor method named getValue() which returns the real value of the fraction object. (Just multiplynumerator by 1.0 and then divide by denominator; return that amount.)• The class has two mutator methods-setNumerator() and setDenominator()-that modify the correspondinginstance variables.• The class has a toString() method that returns the Fraction as a String in the form: 1/2. Use concatenation toproduce the output value.

A class is a group of objects which have common properties. It contains: Fields, Methods,…

Problem Statement Defining Classes Vrite and document the definition for the Fraction class. The Fraction class represents a rational number in the form of a Lumerator and denominator. Fraction Class E Fields denominator : int numerator : int E Methods • Fraction(int num, int denom) * getvalue): double * setDenominator(int denom): void * setNumerator(int num): void toString(): String • Each Fraction object has two int instance variables: numerator and denominator. • The class has one constructor that takes two int parameters in the order numerator, denominator. • The class has one accessor method named getValue() which returns the real value of the fraction object. (Just multipl numerator by 1.0 and then divide by denominator; return that amount.) • The class has two mutator methods-setNumerator() and setDenominator()that modify the corresponding instance variables. The class has a toString() method that returns the Fraction as a String in the form: 1/2. Use concatenation to produce the output value.
