What is a point class in java?

public class Point {
private double x;
private double y;

public Point(double x, double y){
    this.x=x;
    this.y=y;
}public String toString(){
    return "("+ this.x+","+this.y+")";
}
public static void main(String[] args){
    Point point= new Point(3,2);
            System.out.println(point.tostring());
    }
}
