What does final do?
Short answer. It fixes the value, so the variable can be assigned only once.
What error appears if you change it?
Cannot assign a value to final variable DAYS.
Remember
| final: assign only once |
| Name it in UPPER_CASE |
Can a program change the days in a week? It should not. Final makes a constant. Try changing it, and the compiler stops you with an error. Final means assign once. Write the name in capitals.
