The getValue() method The nextInt() method of the Scanner class The nextLine() method of the Scanner class The nextDouble() method of the Scanner class Joan is writing a Java program to check student registrations. To be registered, a student must have paid tuition and selected classes. Two boolean variables provide this information and are populated later in the program. Here are the variable declarations: boolean paidTuition; boolean selectedClasses; To be registered, both variables must be true. Which condition below should Joan use to find registered students?
