Challenge: Building a Server Retry Mechanism

Opgave

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.

  1. Create a method called tryConnect(int successfulAttempt) that returns a boolean indicating whether the connection succeeded.
  2. Inside this method:
    • Start a do-while loop 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 return true.
    • If not, print "Server unavailable, retrying...".
  3. If the loop finishes without success, return false.
  4. In the main method, call tryConnect(...) with a test value and print "Failed to connect to the server after 5 attempts." if the result is false.
