Task
Swipe to start coding
Implement a program that attempts to connect to a server up to 5 times. If the connection is successful, the program prints a success message. If it fails after 5 attempts, it prints an error message.
- Create a method called
tryConnect(int successfulAttempt)that returns abooleanindicating whether the connection succeeded. - Inside this method:
- Start a
do-whileloop that runs up to 5 times. - On each iteration, increment the retry counter.
- If the retry count equals the given
successfulAttempt, print a success message and returntrue. - If not, print
"Server unavailable, retrying...".
- Start a
- If the loop finishes without success, return
false. - In the
mainmethod, calltryConnect(...)with a test value and print"Failed to connect to the server after 5 attempts."if the result isfalse.
