用java语言定义生物类Live，（属性：name名称）它的两个子类分别是动物Animals（属性：color颜色）和植物Plants（属性：color颜色）。其中动物Animals的子类有Cow奶牛类和Sheep绵羊类，（属性：weight体重）。植物Plants类有Tree树类和Flowers类，（属性：height高度）。用程序定义他们之间的关系，要求：对属性进行封装。同时定义无参构造和有参构造。贴上程序

以下是Java语言的程序实现：

public class Live {
    private String name;

    public Live() {
    }

    public Live(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

public class Animals extends Live {
    private String color;

    public Animals() {
    }

    public Animals(String name, String color) {
        super(name);
        this.color = color;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }
}

public class Cow extends Animals {
    private double weight;

    public Cow() {
    }

    public Cow(String name, String color, double weight) {
        super(name, color);
        this.weight = weight;
    }

    public double getWeight() {
        return weight;
    }

    public void setWeight(double weight) {
        this.weight = weight;
    }
}

public class Sheep extends Animals {
    private double weight;

    public Sheep() {
    }

    public Sheep(String name, String color, double weight) {
        super(name, color);
        this.weight = weight;
    }

    public double getWeight() {
        return weight;
    }

    public void setWeight(double weight) {
        this.weight = weight;
    }
}

public class Plants extends Live {
    private String color;

    public Plants() {
    }

    public Plants(String name, String color) {
        super(name);
        this.color = color;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }
}

public class Tree extends Plants {
    private double height;

    public Tree() {
    }

    public Tree(String name, String color, double height) {
        super(name, color);
        this.height = height;
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        this.height = height;
    }
}

public class Flowers extends Plants {
    private double height;

    public Flowers() {
    }

    public Flowers(String name, String color, double height) {
        super(name, color);
        this.height = height;
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        this.height = height;
    }
}

以上程序中，Live是父类，Animals和Plants是Live的两个子类，Cow、Sheep、Tree和Flowers是Animals和Plants的子类，分别包含各自的属性和方法。其中，属性都进行了封装，可以通过getter和setter方法进行访问和修改。同时，每个类都定义了无参构造和有参构造方法，便于对象的创建。
