Problem description
Write a program that will read in a file of student academic credit data and create a list
of students on academic warning. The list of students on warning will be written to a file.
Each line of the input file will contain the student name (a single String with no spaces), the
number of semester hours earned (an integer), the total quality points earned (a double).
The program should compute the GPA (grade point or quality point average) for each student
(the total quality points divided by the number of semester hours) then write the student
information to the output file if that student should be put on academic warning. A student
will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester
hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other
students. Do the following:
1. Create a text data file "students.dat". The following shows part of a typical data file:
Smith 27 83.7
Jones 21 28.35…
Sum of Numbers in a String Create an application that lets the user enter a string containing series of numbers separated by commas. Here is an example of valid input: 7,9,10,2,18,6 The program should calculate and display the sum of all the numbers.
This application accepts an arbitrary number of user inputs. Every time this application receives a string, it should add the string to a growing string.Newly added strings should be added to the growing string at the index equal to the newly added string's length.

Each name should be followed by a hard return (do not store them in a list). Main Function. Write a program where the user enters a name. Using the read function, check to see if the name is in the text document. If it is, respond back to the user the name is found within the list. Read Function.
