java实现判断一个经纬度坐标是否在一个多边形内（经自己亲测）

1.在高德地图上绘制的多边形；经纬度逗号分隔格式；上面是用来方便存坐标的对象；下面是方法测试；直接复制代码即可运行

public class Point {
    
       private Double x;  
        private Double y;  
        public Point (Double x , Double y) {  
            this.x = x;  
            this.y = y;  
        }  
        public Double getX() {  
            return x;  
        }  
        public void setX(Double x) {  
            this.x = x;  
        }  
        public Double getY() {  
            return y;  
        }  
        public void setY(Double y) {  
            this.y = y;  
        }      
}
