Urgent Quick Question Write an equals method for the StepsFitnessTracker class that tests whether the one object is equal to another object that is passed as an argument (Object otherObject). The Object superclass provides an equals method that tests if two object references are equal. Your new equals method should override the Object equals method, and should test the following: • Return true if the current (this) object, and otherObject are identical references (hint: you can use the == operator for this). • Returns false if otherObject is null. • Returns false if the current (this) object and otherObject have different classes (hint: you can use the getClass() method provided by the Object superclass, see the Java 8 API documentation for details). • Casts otherObject to a StepsFitnessTracker, and tests for equality of each instance variable1 , if the instance variables are the same the method should return true.  Now write an equals method for the DistanceFitnessTracker and…
