    Default decimal to hex

    i just need to be able to convert a (maximum) 3 digit decimal number to hex

    Is this the best way to do it, or is there a simple way that i dont see?
    (excluding any built in hex functionality for java)

    public String fullConversion(int n)
    String result = "";
    result += convertSingleNumber(n/256);
    n = n%256;
    result += convertSingleNumber(n/16);
    n = n%16;
    result += convertSingleNumber(n);
    return result;
    private String convertSingleNumber(int i)
    String hex="";
    if(i > 9)
    hex += (char)('A'+((i%10)));
    hex += i;
    return hex;

    Default Re: decimal to hex

    That probably is the best way to do it without any built in functions
