Question $3$: $(35$ pts$)$

Problem: Voting system

Write a Java program that simulates a simple voting system for an election. The program should allow users to vote for one of several candidates, count the votes, and display the results.

The program should allow the following actions:

Vote for a Candidate: Users will vote for one of the predefined candidates.

Display Results: After a user decides to stop voting, the program should display the total votes for each candidate and declare the winner.

Exit: Users can exit the voting process at any time.

You should keep track of the total number of votes for each candidate. If a user enters an invalid candidate name, the program should display an error message and prompt them to try again. After voting ends, the program should display the number of votes for each candidate and the winner $($the candidate with the most votes$).$

The program should have three candidates:

Alice

Bob

Charlie

The voting process should continue until the user types "exit". If an invalid candidate name is entered $($i$.$e$.,$ not Alice, Bob, or Charlie$),$ the program should display an error message and prompt the user to try again.Enter your vote $($or type "exit" to finish$)$: AliceEnter your vote $($or type "exit" to finish$)$: DaveInvalid candidate!
