int a=Character.getNumericValue(c);
System.out.println(a);
}}

What is nextInt ()?

nextInt() method Scans the next token of the input as an int.An invocation of this method of the form nextInt() behaves in exactly the same way as the invocation nextInt(radix), where radix is the default radix of this scanner.
