    • Prompt the user for binary number.
    • Initialize the object “obj” for “Scanner” class.
    • Define the variable “binary” and get the value.
    • Call the “toDecimalvalue()” to calculate the decimal number.
    • Calculate the decimal number using “stream” class and print the value on screen.
  • Define the method “toDecimalvalue()” which takes array list as parameter.
    • Declare the character variable “ans” in type of character.
    • Using “for” loop, assign all list values into “ans[]”.
