Question

public static void main(String args[]) throws IOException {

        Scanner scanner = new Scanner(new File("D:/RAMerrors.txt"));
        String result;
        Double decimal;

        while (scanner.hasNextLine()) {
            String line = scanner.nextLine();
            Scanner input = new Scanner(line);
            String hex = input.next();
            result = hexToBinary(hex);
            System.out.println("Binary of " + hex + ":" + result);
            decimal = binaryToDecimal(result);
            System.out.println("Decimal value: " + decimal);          
        }
}

I want to change the system.out.prinln into a system.out.printf, can't figure it out.

Explanation / Answer

Hi

I have modified the code and highlghted the code changes below

Scanner scanner = new Scanner(new File("D:/RAMerrors.txt"));

String result;

Double decimal;

while (scanner.hasNextLine()) {

String line = scanner.nextLine();

Scanner input = new Scanner(line);

String hex = input.next();

result = hexToBinary(hex);

System.out.printf("Binary of %s: %s " ,hex , result);

decimal = binaryToDecimal(result);

System.out.printf("Decimal value: %lf " ,decimal);
