Answer to Question #194888 in Java | JSP | JSF for Ray

Question

You must design a COVID-19 screening application for your campus. The guards at each gate will screen the students and enter their details on the application. :

1. A screening survey which will allow guards to record the students’ screening data.

2. Searching for a student’s details and status.

Technical Requirements:

*The application should make use of Parallel arrays that will hold the details of the student as it is entered along with their status (admitted/not admitted). No more than 300 students will be allowed on campus .

*No student should be allowed access to the campus after 12h00 in the afternoon.

* If a student’s temperature is 38 degrees or more, they will not be allowed entry into the campus.

1.Without writing the pseudocode say what will be in which module(”fillArray()”,”sortArray()”,”displayArray()” )with the information provided above.
