Which statements do NOT WORK in main() (syntax errors or syntax warnings; note that the object student is already created in main())?
1) Student.university = "JKU";
2) student.name = "Walter";
3) System.out.print(student.getName()+"'s University: " + Student.university);  
4) student.setGPA(4.0);
   System.out.print(student.getName()+"'s GPA: " + student.gpa);
