Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have:  a constructor that accepts arguments for the two fields  a method that returns the tract’s area(i.e. length * width)  an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false.  a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…
