JamesCherrill 3,085 A Java char is, by definition, a numeric value that represents a character. So you can freely mix character representations such as 'a' or 'Z' and numeric expressions, eg
int i = 'C'; // i = 67
int j = 'C' - 'A'; // j = 2

theCompiler if i do that then i must have many declarations to be used. im trying to do a very simple password encryption.

JamesCherrill 3,085 Basically you can convert the password string to an array of chars, and do your arithmetic on that in a simple loop - here's some pseudo-code to point you in the direction:
String pw = ... get the password
char[] ca = pw.toCharArray() // now you have the chars separated into the array
loop thru array adding/subtracting some value from each char
pw = new String(ca) // convert char arry back to a String
