You must design a COVID-19 screening application for your campus. The guards at each gate will screen the students . The capabilities and features of the application should include a choice between the following functions:
1. A screening survey which will allow guards to record the students’ screening data.
*No student should be allowed access to the campus after 12h00 in the afternoons regardless of whether capacity has been reached or not.
*If a student’s temperature is 38 degrees or more, they will not be allowed entry into the campus.
A university that you attend requires an application that will print out a Course Report. You are required to create an application with this course data:
COURSE CODE
DISD DIWD DIDM
COURSE NAME
Diploma in Software Development Diploma in Web Development Diploma in Data Metrics
STUDENT NUMBERS
35 28 39
LECTURER
Mr Jones Mrs Smith Mr Ntsinga
In your main class must include a static method to handle the printing of the course report:
COURSE REPORT
Course Diploma in data metrics
Lecturer Mr Ntsinga
venue : venue 1

What is the output of the following Java code?
count = 1;
y = 100;
while (count < 100)

count++;
}
System.out.println("y = " + y + " and count = " + count);
