Note: you can't change anything is already written

Student.java

// toString method: this is a handy way to specify what you want it to look like when you // print a Student object. Without this, printing a student using System.out.println(student) // will print a memory address. The toString method is called implicitly (you don't have to // call it explicitly when you print) public String toString() { return "[" + name + ", " + major + ", " + gpa + "]"; }

1- you need to get data from file

2- print the data

3- print the lowest gpa

4- print student with gpa 4.0

5- sort Alphabetically and print them
