Class UML is as follows:- feet: int- inches : int+ Length()+ Length(newFeet: int, newinches: int)+ getFeet(): int+ setFeet(newFeet: int) : void+ getinches(): int+ setinches(newInches : int) : void+ add(otherLength: Length): Length+ subtract(otherLength: Length): Length+ equals(otherLength: Length): boolean+ compare To(otherLength: Length): int+ toString(): StringLength• Default constructor sets the length of an object to 0 feet & 0 inches• Overloaded constructor sets the length of an object to given feet & inches (inches mustbe in rage)For each data field, define the accessor and mutator methods•add method, adds two length objects and return the result as a length object (feet &inches must be in range)• Subtract method, subtracts two length objects and return the result as a length object(feet & inches must be in range. this object must be larger than otherLength)• toString() method returns a String in format of [ ## ##"]For example:Length meLength = new Length(10, 6);System.out.println(myLength.toString());Will display: 10'6"STAGE 2 | Implement the Length class using the above UML.STAGE 3 | Compile "Length.java" and fix syntax errorsSTAGE 4 | Driver program | Download "TestLength.java' from ZyBooks1) implement the sum method to calculate sum of all the Length objects.order2) Implement the selectionSort to sort all Length objects in ascending or
