    Default Hexadecimal answer rather than decimal

    Bugger in New Zealand means something like "what a mistake" or mess
    I once had a web site oh-bugger.net.nz but people overseas thought I had a sexual problem, so I changed it to dubdubdub.

    Anyway getting back to Java I just tried

    int hexVal = 0x1a;
    System.out.print(" HEX 1a * 4 = " + hexVal*4);


    it gives the answer as 104 but that is in decimal, I wonder how we could get a Hexadecimal answer of 68

    Default Re: Hexadecimal BUGG.....er

    Hey Eric,

    Try this:

    public class Eric2 {
     
        /**
         * JavaProgrammingForums.com
         */
        public static void main(String[] args){
     
            int hexVal = ((0x1a)*4);
     
            System.out.println("Decimal value: " +  hexVal);
     
            String hex = Integer.toString(hexVal);
     
            int i = Integer.parseInt(hex);
            String hex1 = Integer.toHexString(i);
     
            System.out.println("Hexdecimal value: " + hex1);
     
        }
     
    }

    Output:

    Decimal value: 104
    Hexdecimal value: 68
