在java语言中用继承，数组写一个“已知某个农产品的质量和体积，判断农产品属于哪类农产品”的代码

以下是Java语言中用继承、数组写一个“已知某个农产品的质量和体积，判断农产品属于哪类农产品”的代码：

class AgriculturalProduct {
    double quality;
    double volume;
    String type;
    
    public AgriculturalProduct(double quality, double volume) {
        this.quality = quality;
        this.volume = volume;
    }
    
    public String getType() {
        return type;
    }
}

class Rice extends AgriculturalProduct {
    public Rice(double quality, double volume) {
        super(quality, volume);
        this.type = "rice";
    }
}

class Wheat extends AgriculturalProduct {
    public Wheat(double quality, double volume) {
        super(quality, volume);
        this.type = "wheat";
    }
}

class Corn extends AgriculturalProduct {
    public Corn(double quality, double volume) {
        super(quality, volume);
        this.type = "corn";
    }
}

public class Main {
    public static void main(String[] args) {
        AgriculturalProduct[] products = new AgriculturalProduct[3];
        products[0] = new Rice(0.8, 1.2);
        products[1] = new Wheat(0.7, 1.5);
        products[2] = new Corn(0.6, 1.8);
        
        double quality = 0.7;
        double volume = 1.3;
        
        for (AgriculturalProduct product : products) {
            if (quality == product.quality && volume == product.volume) {
                System.out.println("This agricultural product is " + product.getType());
                break;
            }
        }
    }
}

以上代码中，我们定义了一个AgriculturalProduct类，其中包含了农产品的质量和体积，并定义了一个getType()方法，用于获取农产品的类型。然后，我们定义了Rice、Wheat和Corn三个类，分别继承自AgriculturalProduct类，并在构造函数中设置了对应的类型。最后，在Main类中，我们定义了一个AgriculturalProduct类型的数组，用于存储三种不同的农产品，然后根据输入的质量和体积，遍历数组，找到对应的农产品类型并输出。
