Question

Hi, I am getting illegal start of expression on this. Any ideas where the problem may be: public static void main(String args []){ private String name; private double area; private int population; public Country(String name, double area, int population){ this.name = name; this.area = area; this.population = population; } public double getPopulationDensity() { return population / area; } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getArea() { return area; } public void setArea(double area) { this.area = area; } public int getPopulation() { return population; } public void setPopulation(int population) { this.population = population; } } class CountryTest { public static void main(String[] args) { Country country = new Country("United States of America", 3797000, 327000000); System.out.println("Population density of " + country.getName() + " is " + country.getPopulationDensity() + " per square mile"); } }

Answer 1

public class Country {
    private String name;
    private double area;
    private int population;

    public Country(String name, double area, int population) {
        this.name = name;
        this.area = area;
        this.population = population;
    }

    public double getPopulationDensity() {
        return population / area;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getArea() {
        return area;
    }

    public void setArea(double area) {
        this.area = area;
    }

    public int getPopulation() {
        return population;
    }

    public void setPopulation(int population) {
        this.population = population;
    }

    public static void main(String[] args) {
        Country country = new Country("United States of America", 3797000, 327000000);
        System.out.println("Population density of " + country.getName() + " is " + country.getPopulationDensity() + " per square mile");
    }
}
