Java Array with point (coordination)

i want to creat an array in the main method containing point like p={(3,8),(2,8)} with this class

public class Point
{
    private float x,y;

    public Point(){}
    public Point(float abs){this.x=abs;}
    public Point(float abs, float ord){this.x=abs; this.y=ord;}
    public void setPoint(float abs, float ord){this.x=abs; this.y=ord;}
}

I used p[1] = new Point(5,6); but when i tried to call p[1].x i found that x has a private access. any idea.

You can create an array of Points like this:

Point[] points = new Point[] {
    new Point(3,8),
    new Point(2,8)
};

& in order to be able to access the x & y member variables, they should have a public identifier.

public class Point{
    public float x,y;
    ...
}

But the most optimal way to proceed is by creating a getter:

public class Point{
    private float x,y;
    ...

    public float getX() { return x; }
    public float getY() { return y; }
}

then you can access the Point's x & y this way :

Point point = new Point(1,1);
point.getX();
point.getY();
