    • Define main method.
      • 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[]”.
      • Return the value of “ans”.
