Here is an example of a simple stock program written in Java:
public class Stock {
private String name;
private int quantity;
private double price;
public Stock(String name, int quantity, double price) {
this.name = name;
this.quantity = quantity;
this.price = price;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public double getValue() {
return quantity * price;
}
public void buy(int quantity, double price) {
this.quantity += quantity;
this.price = (this.price * this.quantity + price * quantity) / (this.quantity + quantity);
}
public void sell(int quantity) {
if (this.quantity < quantity) {
throw new IllegalArgumentException("Cannot sell more stocks than you have");
}
this.quantity -= quantity;
}
public String toString() {
return "Stock [name=" + name + ", quantity=" + quantity + ", price=" + price + "]";
}
