如何实现一次向一个项目添加类(WayPoints)

public class WayPoints {
    // 类的成员变量和方法可以在这里定义
}

public class WayPoints {
    private double latitude;
    private double longitude;
    
    public WayPoints(double latitude, double longitude) {
        this.latitude = latitude;
        this.longitude = longitude;
    }
    
    public double getLatitude() {
        return latitude;
    }
    
    public double getLongitude() {
        return longitude;
    }
    
    // 其他方法可以在这里添加
}

WayPoints point = new WayPoints(37.7749, -122.4194);
System.out.println("Latitude: " + point.getLatitude());
System.out.println("Longitude: " + point.getLongitude());
