Write a program BinarytoDecimal.java that prompts the user to enter a 4-bit binary number. This number is read as a string, and then converted to decimal. If the bits in the number are bo, b1, b2 and b3, then the output decimal value is computed as 8*b3 + 4*b2 + 2*b1 + bo. For example, the binary number 1100 produces the output 12. Input cmd: java BinarytoDecimal Output: Please enter 4 digit binary: 1100 The decimal value is 12
