More on Loops and Conditional Statements [link]
Source code: Newtab.java Module: J704
public class Newtab {
public static void main (String [] args) { // 1. Define variables and their types int passengers; // Maximum number of passengers double fare; // to hold cost per passenger double totalcost; // to hold total overall price int count; // Current passenger count // 2. Set their initial values fare = 3.95; System.out.print("Up to how many people are travelling? "); passengers = (int)WellHouseInput.readNumber(); // N.B. say that it's OK as an integer // 3. We can now loop through a series of calculations and outputs count = 0; while (count <= passengers) { totalcost = fare * count; System.out.print("With "); System.out.print(count); System.out.print(" passengers, the bill will be "); System.out.println(totalcost); count = count + 1; } /* Sample output: wizard:jn10 graham$ java Newtab Up to how many people are travelling? 7 With 0 passengers, the bill will be 0.0 With 1 passengers, the bill will be 3.95 With 2 passengers, the bill will be 7.9 With 3 passengers, the bill will be 11.85 With 4 passengers, the bill will be 15.8 With 5 passengers, the bill will be 19.75 With 6 passengers, the bill will be 23.70 With 7 passengers, the bill will be 27.65 wizard:jn10 graham$ */ } } Learn about this subject
