CMSC 350 Project 3

CMSC 350 Project 3The third programming project involves writing a program that performs a sort by using a binarysearch tree. The program should be able to sort lists of integers or lists of fractions in eitherascending or descending order. One set of radio buttons should be used to determine whether thelists contain integers or fractions and a second set should be used to specify the sort order. Themain class should create the GUI shown below: The GUI must be generated by code that you write. You may not use a drag-and-drop GUIgenerator.Pressing the Perform Sort button should cause all the numbers in the original list to be added to abinary search tree. Then an inorder traversal of the tree should be performed to generate the listin sorted order and that list should then be displayed in the sorted list text field.In addition to the main class that defines the GUI, you should have a generic class for the binarysearch tree. That class needs a method to initialize the tree, one that allows a new value to beinserted in the tree and one that performs an inorder tree traversal that generates and returns astring that contains the tree elements in sorted order. The insert method does not need torebalance the tree if it becomes unbalanced. It should allow duplicate entries and it must bewritten using recursion. It is not necessary to have a method to delete a node from the tree norone to check whether a particular value is in the tree.The third class required for this project is one that defines fractions. It should have a constructorthat accepts a string representation of a fraction and a toString method. It must implement theComparable interface, which means a compareTo method is also required.A second example of a run of this program is shown below that sorts fractions in descendingorder: Note that fractions are to be written with a slash separating the numerator and denominator withno spaces on either side of the slash.The only error checking required of this program is to check for nonnumeric input whichincludes improperly formatted fractions such as 3/4/8. Such malformed fractions should causea NumberFormatExpression to be thrown. The main class must catch these exceptions anddisplay an appropriate error message as shown below: You are to submit two files.1. The first is a .zip file that contains all the source code for the project, which includesany code that was provided. The .zip file should contain only source code and nothingelse, which means only the .java files. If you elect to use a package the .java filesshould be in a folder whose name is the package name. 2. The second is a Word document (PDF or RTF is also acceptable) that contains thedocumentation for the project, which should include the following:a. A UML class diagram that includes all classes you wrote. Do not includepredefined classes. You need only include the class name for each individualclass, not the variables or methodsb. A test plan that includes test cases that you have created indicating what aspectsof the program each one is testingc. A short paragraph on lessons learned from the project
