A Doctor wishes you to write a program to help him schedule patient appointments

Question

A Doctor wishes you to write a program to help him schedule patient appointments. He wants you to give a patient a choice between two days, then a choice between morning or afternoon, and finally a time. He than wants you to display the appointment. You will be using if-else statements as well as the JOptionPane class. • The class name should be AppointmentScheduler. • Display a good introduction screen You are to use only three showInputDialogue methods and two showMessageDialogs statements within your source code, including the program introduction. • The information from each successive data entry must be included in the next prompt. • You may choose any two days you want - have the user enter the first letter of the day (enter m for Monday), same for the time (enter m for Morning or a for Afternoon), then have the user enter a time. • You may phrase your prompts how you want. I need this in JAVA. Thank you!
