1.创建一个代表天气对象的实体类 a)拥有私有属性:日期，地点，⻛速，温度，湿度 b)拥有属性的get，set公有方法

可以使用以下代码创建一个代表天气对象的实体类：

public class Weather {
    private String date;
    private String location;
    private double windSpeed;
    private double temperature;
    private double humidity;

    public Weather(String date, String location, double windSpeed, double temperature, double humidity) {
        this.date = date;
        this.location = location;
        this.windSpeed = windSpeed;
        this.temperature = temperature;
        this.humidity = humidity;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getLocation() {
        return location;
    }

    public void setLocation(String location) {
        this.location = location;
    }

    public double getWindSpeed() {
        return windSpeed;
    }

    public void setWindSpeed(double windSpeed) {
        this.windSpeed = windSpeed;
    }

    public double getTemperature() {
        return temperature;
    }

    public void setTemperature(double temperature) {
        this.temperature = temperature;
    }

    public double getHumidity() {
        return humidity;
    }

    public void setHumidity(double humidity) {
        this.humidity = humidity;
    }
}

这个类拥有私有属性date、location、windSpeed、temperature、humidity，以及对应的公有getter和setter方法。可以通过构造函数或者setter方法来设置这些属性的值。
