Read a hexadecimal number
// Create a scanner object Scanner myObj = new Scanner("FFAD01");
// Change radix myObj.useRadix(16);
// Read and display the number System.out.println(myObj.nextInt());Definition and Usage
The useRadix() method changes the radix used by the scanner. The radix specifies how many different symbols can be used to represent each digit in a number. For example, a radix of 16 would allow the symbols 0 to 9 and A to F to be used as digits.
