NEED THESE ASAP

Expert Solution

Implement the program as follows:

import Scanner class
define class Single
define private member unique
define a constructor that accepts float value, unique
set float value unique
define setter method setUnique() that accepts float value unique
set float value unique
define getter method getUnique()
return unique value
define the method toString()
return string representation of Single class
define the method main()
Instantiate Single class
print Single class object
update unique using setUnique()
print Single class object
define variables to store hours, minutes and seconds
initialize Scanner
ask the user to enter time interval in seconds
read time interval
calculate seconds as time_seconds%60
calculate total_minutes as time_seconds/60
calculate minutes as total_minutes%60
calculate hours as total_minutes/60
print time interval as hours, minutes and seconds

Program: Single.java

Language: Java
