 Fruits.java

public class Fruits {

    private String name;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public double getPrice() {
        return price;
    }
    public void setPrice(double price) {
        this.price = price;
    }
    public String getProducing_area() {
        return producing_area;
    }
    public void setProducing_area(String producing_area) {
        this.producing_area = producing_area;
