Java - Change int to ascii

Question

Is there a way for java to convert int\'s to ascii symbols?

Answer 1

In Java, you really want to use Integer.toString to convert an integer to its corresponding String value. If you are dealing with just the digits 0-9, then you could use something like this:

private static final char[] DIGITS =
    {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

private static char getDigit(int digitValue) {
   assertInRange(digitValue, 0, 9);
   return DIGITS[digitValue];
}

Or, equivalently:

private static int ASCII_ZERO = 0x30;

private static char getDigit(int digitValue) {
  assertInRange(digitValue, 0, 9);
  return ((char) (digitValue + ASCII_ZERO));
}
