    Default how can a rectangle of an Image intersect with a mouse cursor?

    im already a bit familiar of how does rectangle is used and important in manipulating images for an animation (COLLISIONS),

    but how can i make a statement that will detect that a rectangle of an object(image) has been intersected by a mouse cursor, i have no more questions about mouselisteners i just want to know how to get the BOUNDS of a mouse cursor, and is it possible?

     
      if (myImageRectangle.intersects my mouse rectangle) { // i dont know if this is fairly easy to do or possible in some way
     
                 < do something here>
      }

    finally got it (e.getComponent().getBounds()) , but i thought it will solve the issue of what i want,
    i think i need to rephrase what i need, sorry to make my statements a little bit confusing

    how can i detect IF I CLICKED or PRESSED an IMAGE(vice versa on RELEASE event) ? - i think im confident with my statement here as it is expressing my main concern

    how can i detect IF I CLICKED or PRESSED an IMAGE
    Get the cursor's/mouse's x,y position and see if it is in the rectangle where the image is.

    Get the cursor's/mouse's x,y position and see if it is in the rectangle where the image is.
    i tried with different getX(), point, of the mouse components , still im having some problems, but anyways, i just manually set a number where the mouse's X will intersects and do something

    im having some problems,
    Please explain. Add some printlns to your code to show the mouse's location and the rectangle's location.
    Then click on different parts of the rectangle and see what x,y is printed out for that location.

    oh sorry i didnt make it clear, i think the image's dimension's itself has some problems, that why my mouse's point(x and y) is not exactly intersecting with the image's rectangle bounds(x and y),

    It's hard to know if a point is in a rectangle if you don't know where the rectangle is.
    How do you show the image that you can't get its position?
