Write a program that reads the contents of a text file. the program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. for example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. the program should either display the frequency of each word or create a second file containing a list of each word and its frequency.

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student.java, undergraduatestudent.java, graduatestudent.java, studentatlarge.java, and studentdemo.java.
