System.out.println(person.toString() + " "); System.out.println(student.toString() + " "); System.out.println(employee.toString() + " "); System.out.println(faculty.toString() + " "); System.out.println(staff.toString() + " "); } } I keep getting error "non static variable this cannot be referenced from a static context" and I am out of ideas. The code is question is

public static void main(String[] args) { // create objects for classes Person person = new Person("John Doe", "123 Somewhere", "415-555-1212", "johndoe@somewhere.com"); Person student = new Student("Mary Jane", "555 School Street", "650-555-1212", "mj@abc.com", "junior"); Person employee = new Employee("Tom Jones", "777 B Street", "408-888-9999", "tj@xyz.com"); Person faculty = new Faculty("Jill Johnson", "999 Park Ave", "925-222-3333", "jj@abcxyz.com"); Person staff = new Staff("Jack I. Box", "21 Jump Street", "707-212-1112", "jib@jack.com");
