simple System.out.println Java program

How do I solve this error, Error:(22, 28) java: variable msb might not have been initialized: Please fix the error also. You can ignore line 14 to 18, I'm really focused on 20 to 28. After the user types a set of number, the largest number gets saved to the variable. How do I solve this issue?

Help with:

1. System.out.println("blah blah" + maxDigit(msb));

2. Put a limit, the user must enter no more than 3 digits for int msb.

Please send me a photo. If you don't want to or can't, you can paste the answer. Thank you in advance!
