public class Point {

        y = b;
    }
    public double distance(double x，double y){

    }
   
    public static void main(String[] args) {
        // TODO Auto-generated method stub

我这个程序应该存在问题，但是我不知道如何去修改

引号里面打错了，应该是"两点间的距离为："

public class Point {

    private double x,y;
    public Point(double a,double b){
        x = a;
        y = b;
    }
    public double getX(){
        return x;
    }
    public double getY(){
        return y;
    }
    public double distance(Point p){
        return Math.sqrt(Math.pow(x-p.getX(),2)+Math.pow(y-p.getY(),2));
    }
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Point One = new Point(1,1);
        Point Two = new Point(1,3);
        System.out.println("这个点到到原点距离为:" +One.distance(Two);//我想在这里直接输出两点距离
    }
}
