Write a program that reads a 4-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is 1100, theoutput should be 12. (Hint: Break the string into substrings and then convert each substring to a value for a single bit . If the bits are b0, b1, b2, and b3, the decimal equivalent is 8b0+ 4b1+ 2b2+ b3.)
Input Notes: Just a 4-bit  string , like 1101 or 0010.

Output Notes (Prompts and Labels): The input is prompted for by:
        Enter a four bit binary value .
After input, the program prints out a line of this form:
        The value of BBBB is D
where BBBB is the binary string entered and D is the calculated decimal equivalent.

SPECIFICATION OF NAMES: Your application class should be called FromBinary
