What should I replace in the following code with n = int(input("Enter n"))isvalid = Truei = 2while i*i <= n: if n%i == 0: isvalid = False else: isvalid = i += 1 if isvalid: print("n is prime")else: print("n is not prime")

Write the quartstogallons java class that declares a named constant to hold the number of quarts in a gallon (4). also declare a variable to represent the number of quarts needed for a painting job, and assign an appropriate value—for example, 18. compute and display the number of gallons and quarts needed for the job. display explanatory text with the values, for example:
