用java写个类人模型

好的，以下是一个简单的Java类人模型的代码，具有基本的属性和方法：

public class Human {
    private String name;
    private int age;
    private String gender;
    private double height;
    private double weight;

    public Human(String name, int age, String gender, double height, double weight) {
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.height = height;
        this.weight = weight;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getGender() {
        return gender;
    }

    public double getHeight() {
        return height;
    }

    public double getWeight() {
        return weight;
    }

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

    public void setAge(int age) {
        this.age = age;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

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

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

    public void introduce() {
        System.out.println("Hi, my name is " + name + ", I am " + age + " years old, " + gender + ", my height is " + height + "cm and my weight is " + weight + "kg.");
    }

    public double calculateBMI() {
        return weight / ((height / 100) * (height / 100));
    }
}

这个类包含了人的基本属性，如姓名、年龄、性别、身高和体重，以及介绍自己和计算BMI的方法。我们可以在其他类中创建Human对象，并使用它的方法和属性。例如，我们可以这样使用：

public class Main {
    public static void main(String[] args) {
        Human person = new Human("Tom", 20, "Male", 180, 70);
        person.introduce();
        System.out.println("My BMI is " + person.calculateBMI());
    }
}

这里我们创建了一个名为Tom、年龄20岁、身高180cm、体重70kg的男性。然后我们使用introduce方法介绍他自己，并使用calculateBMI方法计算他的BMI。
