Create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate and undergraduate. Out-of-state undergraduate students pay twice the tuition of Florida-resident undergraduate students (all students pay the same health and id fees). A graduate student is either a PhD or a MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Ms and Phd student must be a teaching assistant for one undergraduate course. MS students can only take graduate courses. A course with a Course Number (crn) less than 5000 is considered an undergraduate course, and courses with a 5000 crn or higher are graduate courses.

Tape for a Turing Machine (Doubly-linked List)”.(I USE ECLIPSE & RUN CHECK ONLINE CONSOLE)A class named Tape to represent Turing machine tapes. The class should have an instance variable of type Cell that points to the current cell with the method: public Cell getCurrentCell() -- returns the pointer that points to the current cell. public char getContent() -- returns the char from the current cell. public void setContent(char ch) -- changes the char in the current cell to the specified value. Don't forget the Javadoc comments. IT WOULD HAVE A PUBLIC CLASS public void moveLeft() -- moves the current cell one position to the left along the tape. Note that if the current cell is the leftmost cell that exists, then a new cell must be created and added to the tape at the left of the current cell, and then the current cell pointer can be moved to point to the new cell. The content of the new cell should be a blank space. (Remember that the Turing machine's tape is conceptually…
