Hello everyone Hope all are well Just new here & already have a question.

And add the price together. oh each item has a price eg apples = .30 ect my problem is I can only buy 3 of the above items without using loops or switch or while Im beginner so only if and nested if and else if This has my head in bits for days I have the below done x6 for each product How i get it to 3 (without throwing the other 3 items away)

double oPrice, orangesCost; int oQuantity; oPrice = 0.45; System.out.println(" \t\t Product Price Calculation"); System.out.print("Enter quantity of oranges required "); oQuantity = in.nextInt(); orangesCost = oPrice * oQuantity; //calculate final cost by adding tax String fs2 = String.format(" your oranges will cost you: %.2f", orangesCost); System.out.println(fs2);
