This program starts with the Student class from earlier. We want to add a new instance variable (or field) that represents the students GPA. Since it can contain a decimal place, youll need to figure out the right type. You should also add the GPA to the toString method and use it to print out the following: Alan Turing is in grade: 11 and has GPA: 3.5 Ada Lovelace is in grade: 12 and has GPA: 3.8
