【问题描述】 编辑Person类,有两个double类型的私有成员变量weight、height,需要为每个成员变量设计get/set方法 注意: weight的准则是大于400或者小于0时,默认赋值70.0 height的准则是大于300或者小于0时,默

编辑`Person`类，你可以按照以下步骤创建双属性`weight`和`height`，并添加相应的getter和setter方法。同时，为了满足提供的条件，可以在setter方法中加入检查：

public class Person {
    private double weight;
    // 默认值为70.0
    private double height;

    public Person() {
        this.weight = validateWeight(70.0);
        this.height = validateHeight(0.0);
    }

    // Getters and Setters with validation
    public double getWeight() {
        return weight;
    }

    public void setWeight(double weight) {
        if (weight <= 0 || weight > 400) {
            System.out.println("Invalid weight, setting to default value 70.0");
            this.weight = 70.0;
        } else {
            this.weight = weight;
        }
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        if (height <= 0 || height > 300) {
            System.out.println("Invalid height, setting to default value 0.0");
            this.height = 0.0;
        } else {
            this.height = height;
        }
    }

    // Validation methods
    private double validateWeight(double defaultValue) {
        return Math.max(defaultValue, Math.min(weight, 400));
    }

    private double validateHeight(double defaultValue) {
        return Math.max(defaultValue, Math.min(height, 300));
    }
}

在这个版本的`Person`类中，设置重量和高度时会先进行有效性检查，如果不符合条件，则自动采用默认值。
