Question

Please make a Java program that has a menu method and includes dialog boxes. The program will call the proper method, but each method will be completed later. Your program will keep track of information for a Hospital. The program will be menu-driven. Your menu is to look something like the following:

UPMC Medical Center

1. Add/Modify Patient Information
2. Add/Modify Physician Information
3. Add/Modify Medical Information
4. Hospital Report Section
5. Exit the Medical System

Please Make your selection >

In this first phase, you are to write the complete method for the menu and stubs for all of the other methods.

The names and definitions of the methods are as follows:

1. Main_Menu – This method is NOT a stub…This method will print the above menu and will return the user’s selection to the main method. (You will have a while loop in the main JAVA method that calls the menu method until the user selects #5)

All of the following must be done in the main method (in this order): This is the pseudo-code to follow post-directions

1. Write the java statement to call the method read_patient
2. Write the java statement to call the method read_doctor
3. Write the java statement to call the method read_medical
4. Write the java statement to call the method Main_menu and pass back the user’s selection
5. Write a While loop that will run until (the selection is not equal to 5)

6. Begin the loop

7. If the selection is equal to 1 write the Java statement to:

call the method Modify_patient

8. If the selection is equal to 2 write the Java statement to:

call the method Modify_physician

9. If the selection is equal to 3 write the Java statement to:

call the method Modify_medical

10. If the selection is equal to 4 write the Java statement to:

call the method Report_section

10. Write the Java statement to Call the method Main_menu and pass back the user’s selection

   11. End the while loop

12. Write the Java statement to call the method Exit_upmc
