JAVA
I have an error on this code saying “error: class, interface, or enum expected ShipTester”
Can you help determine the problem?
java
import java.util.Scanner;
class Ship {
private String shipName;
private int yearBuilt;
public Ship(String shipName, int yearBuilt) {
this.shipName = shipName;
this.yearBuilt = yearBuilt;
}
public String getShipName() {
return shipName;
}
public void setShipName(String shipName) {
this.shipName = shipName;
}
public int getYearBuilt() {
return yearBuilt;
}
public void setYearBuilt(int yearBuilt) {
this.yearBuilt = yearBuilt;
}
}
class CruiseShip extends Ship {
private int maxPassengers;
public CruiseShip(String shipName, int yearBuilt, int maxPassengers) {
super(shipName, yearBuilt);
this.maxPassengers = maxPassengers;
}
public int getMaxPassengers() {
return maxPassengers;
}
public void setMaxPassengers(int maxPassengers) {
this.maxPassengers = maxPassengers;
}
public double calculateIndividualCost() {
if (maxPassengers >= 1000) {
return 500.0;
} else if (maxPassengers >= 500) {
return 750.0;
} else {
return 1000.0;
}
}
}
public class ShipTester {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter ship name: ");
String shipName = scanner.nextLine();
System.out.print("Enter year built: ");
int yearBuilt = scanner.nextInt();
System.out.print("Enter max number of passengers: ");
int maxPassengers = scanner.nextInt();
CruiseShip cruiseShip = new CruiseShip(shipName, yearBuilt, maxPassengers);
System.out.println("\nShip Information:");
System.out.println("Ship Name: " + cruiseShip.getShipName());

System.out.println("Max Passengers: " + cruiseShip.getMaxPassengers());
double individualCost = cruiseShip.calculateIndividualCost();
