How to check the number of digits in an integer 1

[thelordoftherings]

Hello,

I have an arbitrary int value and I would like to check how many digits this integer has (For example: 367 has 3 digits...). How can I do it?

String.valueOf(yourInt).length();

Cheers,
Dian

Note that integers can be negative, so the solution posted above, which basically just counts how many characters are required to render the integer as text will not work for negative integers (as the first character will be the '-' character indicating a negative number).

I suggest taking the absolute value of the integer (so if it is -ve it will become positive, and if it is +ve it will not be changed) and then applying the above method.

Good point.

Math.abs() would do the job.
