Printing click coordinates. Build a custom subclass of JComponent which listensfor MouseEvents, after observing a click, it should just print the coordinates, as in"Click detected at (X,Y)." (but with actual coordinates for X and Y). This meansyour class should also implement the MouseListener interface, and register itself asa listener in the constructor. Write a main method which creates a new JFrame andadds an instance of your class to the frame. Name your custom class EventLabCanvas(or anything else you prefer. You may want to refer to lecture code posted on May30th to get started.2. Drawing circles centered on clicks. Add code to make your canvas draw a smallfilled circle on itself when it receives a mouseClicked event. The circle should becentered on the location of the click. (Hint: use JComponent.getGraphics () andGraphics.fil10val() in your implementation of the mouseClicked method.)3. Connecting circles with lines. Modify your canvas so that it draws lines betweenthe centers of the circles as you create them. See Figure 1 for an example. Hint:use instance variables to store most recent click coordinates (or MouseEvent) andgetGraphics () and Graphics.drawLine () to draw the line in mouseClicked)Make circles draggable when placing them. Have your program draw smallfilled circles as the mouse is dragged, and make the connecting line move too. UseGraphics.setColor and set color to Color.WHITE to erase the previous graphic whendragging. You will need to implement the MouseMotionListener interface, and tocall addMouseMotionListener as appropriate.4.
