c) A private constant (final) int data field named APPOINTEMENT_ID.
d) A private int data field named dayhe value represents the day of the week from 1 to 5, (1 for Monday, 2
for Tuesday, and so on till Friday).
e) A private int data field named hour. Accepted values are 8, 9, 10, …14

appointment will be immediately assigned a APPOINTEMENT_ID according to newID.
g) The accessor (getter) methods for patientName and APPOINTEMENT_ID.
h) The accessor and mutator (setter) methods for the day and hour fields. Note that if the day value is not in
[1,5] then the field is set 0. Also, if the hour is not in [8,14], the field value is set to 0.

A cache of Hebrew manuscripts known as the Dead Sea Scroll was found in 1947. The specific activity of Carbon-14 in the linen wrappings of the book of Isaiah was about 0.200 disintegration per second per gram (dps g-1.). Carbon-14 in living materials has
a specific activity of 0.255 dps g-1. The half-life of Carbon-14 is
5.73 x103 years. Carbon-14 decay by First order rate law. Calculate the approximate age of the linen.
