Complete the following method, whose purpose is to add the value of its parameter to a field named value1. * Add value to the given costPrice */ public void calc(int costPrice) { ++ } O A. price = price - amount B.value1 = value1 + costPrice: OC. costPrice = costPrice + value1; O D. costPrice = amount + value 1; Suppose the header statement below is provided in UpdateValue class. How can you tell from just its header that setValue (below) is a method and not a constructor? public double setValue (float inpValue). Solution options: (1) Its header has a return type and constructors do not have return types (2) It does not have the same as the class it is in. (3) The first letter of "setValue" is lower case! O A. Option (1) O B. Option (2) O C. Option (3) O D. Options (1), (2), and (3)
