Java Forum / First Aid / September 2006Convert from int to char
Okay, so i have a dilemma. I have a int variable called rank that stores integers (obviously). however, i need to display these values as chars in another method. casting dosent help because it just converts the integer into the unicode character which isn't the same as the number. heres a snippet of the problem: char r; // as you can see, its gets pretty repetitive and boring if (rank == 2) r = '2'; if (rank == 3) r = '3'; if (rank == 4) r = '4'; .... return r; is there a trick to make my int number the equivalent char number? > Okay, so i have a dilemma.

Does Character.forDigit() do what you want? Patricia > Okay, so i have a dilemma.

Roedy has an online applet, on his website, that will let you select the from and to Object types and offer the available Java statement to do the conversion. http://mindprod.com/applets/converter.html You can also download it also.

I'm going to guess that you really mean that you want to convert it to a character string, to display in a textbox or the like. The trick is to use String.format To convert your integer to a string, use String r = String.format("%d", rank); hth /js > is there a trick to make my int number the equivalent char number? char r = '0' + rank; > Okay, so i have a dilemma.

The following single line should do what you want: char r = (char) (rank+48); as the ascii characters 0-9 equte to 48, 49, 50 ... 57.
