(Solved) : Use Interface Listinterfacejava Add New Class Models Student Stored Node Data Field Studen Q35577786

Use the interface “ListInterface.java”

  1. Add a new class that models a Student to bestored in the Node as the data field.
  2. Student class should have this content:
    1. Data members: id, first name, last name,gender, department, credits & gpa.
    2. Methods: default constructor, rand, toStringand list. These methods are explained as follows:
      • default constructor: sets all data members tovalues of your choice but need to be justified.
      • rand: randomly generates an instance ofStudent by setting all data members to random values.
      • toString: returns a string containing all datafields in one line.
      • equals: test if two Students have identicalobject content.
      • list: creates and returns a “ArrayList” ofStudent objects.
  3. Add a new method to HTLinkedList (Head to tail LinkedList)“print” that prints all objects contained in the list.
  4. Add a Driver/Demo/Test class to test the methods ofHTLinkedList.
  5. Test your project and screen-capture your sample testing to besent along with the project.
