My professor wants me to: Write a program that prompts the user for a binary number (from 3 to 8 bits) as a String and converts it to base-10 decimal value. With a for loop which I have in the program, I need help prompting the user to only use 3 to 8 bits. public static void main(String args[]) { System.out.println("Enter a binary number: "); Scanner scan = new Scanner(System.in); String s = scan.next(); long result = 0; for (int i = 0; i < s.length(); i++) { result = (long) (result + (s.charAt(i) - '0') * Math.pow(2, s.length()- i - 1)); scan.close(); } System.out.println(result); }
