class Product {
private int stock;
public Product(int stock) { this.stock = stock; }
public String checkStock() {
if (stock > 0) return "In stock";
else return "Out of stock";
}
}Answer and explanation
Correct answer
C. "In stock"
Why
The method checkStock() checks if the product's stock is greater than zero. If it is, it returns "In stock". Since the stock is 10, which is greater than zero, "In stock" is returned.
