Supply a static method that computes the number of binary digits in a given integer. For example,


should return 5 because 20 is 101002.

Complete the following file:

public class Numbers { /** Returns the number of digits in the binary representation of a number @param n a nonnegative number @return the number of binary digits needed to represent n */ // TODO: supply the method . . . public static void main(String[] args) { System.out.println(Numbers.binaryDigits(20)); } }
