How to get Line Selected

When i click near the line line gets selected but i want the line to be selected when exactly i click on the line not outside the line...I tried with the following code but line gets selected when i click outside, here mouseX and mouseY are the position where i click mouse;
so help please;


Line2D.Double ln = new Line2D.Double(xPos,yPos,xPos2,yPos2);

Code:

---

boolean isSelected(double mouseX, double mouseY)
        {
                if (mouseX > (xPos - xPos2) && mouseX < (xPos + xPos2) &&
                                  mouseY > (yPos - yPos2) && mouseY < (yPos + yPos2))
                                selected = true;
                else
                                selected = false;
                return selected;
        }
