java农夫果园代码

以下是一个简单的Java农夫果园代码示例，其中包含了农夫、果树和水果等类的定义，以及一些基本的操作方法。

// 农夫类
public class Farmer {
    private int id;
    private String name;
    
    public Farmer(int id, String name) {
        this.id = id;
        this.name = name;
    }
    
    public int getId() {
        return id;
    }
    
    public String getName() {
        return name;
    }
    
    public void waterTree(Tree tree) {
        tree.setWatered(true);
        System.out.println("农夫" + name + "给果树" + tree.getId() + "浇水了。");
    }
    
    public void harvestFruit(Tree tree) {
        if(tree.isWatered()) {
            Fruit fruit = tree.harvest();
            System.out.println("农夫" + name + "采摘了果树" + tree.getId() + "上的" + fruit.getName() + "。");
        } else {
            System.out.println("果树" + tree.getId() + "还没有浇水，无法收获果实。");
        }
    }
}

// 果树类
public class Tree {
    private int id;
    private Fruit fruit;
    private boolean watered;
    
    public Tree(int id, Fruit fruit) {
        this.id = id;
        this.fruit = fruit;
    }
    
    public int getId() {
        return id;
    }
    
    public Fruit getFruit() {
        return fruit;
    }
    
    public boolean isWatered() {
        return watered;
    }
    
    public void setWatered(boolean watered) {
        this.watered = watered;
    }
    
    public Fruit harvest() {
        Fruit fruit = this.fruit;
        this.fruit = null;
        return fruit;
    }
}

// 水果类
public class Fruit {
    private String name;
    
    public Fruit(String name) {
        this.name = name;
    }
    
    public String getName() {
        return name;
    }
}

// 示例程序
public class Orchard {
    public static void main(String[] args) {
        Fruit apple = new Fruit("苹果");
        Tree tree1 = new Tree(1, apple);
        Farmer farmer1 = new Farmer(1, "张三");
        
        farmer1.waterTree(tree1);
        farmer1.harvestFruit(tree1);
    }
}

在该示例中，定义了农夫、果树和水果三个类，其中农夫可以给果树浇水和收获果实，果树可以存储水果和记录是否已经浇水，水果类只有一个名称属性。示例程序创建了一个苹果树和一个农夫，农夫先给果树浇水，然后收获果实。
