    private String number;
    private int price;
    
    public String getMaterial() {
        return material;
    }
    public void setMaterial(String material) {

        this.price = price;
    }
    
    public Table(String material, String number, int price) {
        super();
        this.material = material;
        this.number = number;
        this.price = price;
    }
    
    public void table(){
        System.out.println("型号："+this.number+"\n材质："+this.material+"\n价格："+this.price+"元");
        System.out.println();
        }
}

package Homework;

public class TestTable {
    
    public static void main(String[] args) {

}

第四题：

写一个传奇游戏中的猪类，类中有属性：颜色(color)、重量(weight)、攻击力(attack)、准确度(accuracy)。

再写一个测试类，生成一个猪的对象，将此猪的颜色值为“白色(white)”，重量为5，攻击力为50点，准确度为0.8。

要求输出此猪的信息格式为：一只白色的猪，重量5，攻击为50点血，准确度为0.8，我好怕怕呀

package Homework;

public class Pig 
{
    private String colour;
    private int weight;
    private int attact;
    private double accuracy;
    
    public String getColour() {
        return colour;
    }
    public void setColour(String colour) {
        this.colour = colour;
    }
    public int getWeight() {
        return weight;
    }
    public void setWeight(int weight) {
        this.weight = weight;
    }
    public int getAttact() {
        return attact;
    }
    public void setAttact(int attact) {
        this.attact = attact;
    }
    public double getAccuracy() {
        return accuracy;
    }
    public void setAccuracy(double accuracy) {
        this.accuracy = accuracy;
    }
    
    public Pig(String colour, int weight, int attact, double accuracy) {
        super();
        this.colour = colour;
        this.weight = weight;
        this.attact = attact;
        this.accuracy = accuracy;
    }
    
    public void pig()
    {
        System.out.println
        ("一只"+this.colour+"的猪，"+
         "重量"+this.weight+
         ",攻击为"+this.attact+"点血，准确度为"+
                this.accuracy+"，我好怕怕呀~");
    }
    
    
}

package Homework;

public class TestPig {

    public static void main(String[] args) {
        
        Pig myPig=new Pig("白色",5,50,0.8);
        myPig.pig();

    }

}
