Trying to move airplane by clicking on it each time.

**I created two aircraft's for my first project.Then for my next project, I have to be able to make it move horizontally one step every time I click on the body, and move vertically every time I click on any of the wings. I started by creating first a class body that extended to RoundedRectangle but I got errors with the MouseClicked event and I was not able to move the object. Can anybody help me out with what I am doing wrong? Or what I need to do in order to make it move horizontally and vertically? **

        _backWing.setLocation(x+245,y+15);
    }
    
}

**AND this is the App class:**

    import wheels.users.*;
    import java.awt.Color;


    public class AirApp extends Frame {
    private Aircraft _airc1, _airc2;// created another aircraft here.

	public AirApp() {
		_airc1 = new Aircraft(Color.blue, Color.green, Color.green, Color.green);
		_airc1.setMessage("Hey look, I am way higher than you!", 130,10);
		_airc1.setLocation(300,50);
		
		_airc2 = new Aircraft(Color.red, Color.pink, Color.gray, Color.orange);
		_airc2.setMessage("Oh yeah? but I am flying faster than you!", 0,250);
		_airc2.setLocation(100,350);
	}

	public static void main(String [] args) {
	    AirApp app = new AirApp();
	}

}

**Then i created a Body class that extends Rounded Rectangle and here it is:**

    import wheels.users.*;
    import java.awt.Color; 
    import java.awt.event.MouseEvent;

    public class Body extends RoundedRectangle {
    
    private java.awt.Point _lastMousePosition, _currentPoint;
    
    private int _x, _y;
 
    public Body(java.awt.Color aColor, int x, int y, int l, int w) {
        super(aColor);
        this.setLocation(x,y);
        this.setSize(l,w);
        
        _lastMousePosition = new java.awt.Point();
    }    
        
    public Body () {
    }    
    public void mouseClicked (MouseEvent e) {
        _lastMousePosition = e.getPoint();
        
    }
    public void mouseReleased (MouseEvent e) {
        _currentPoint = e.getPoint();
        int diffX = _currentPoint.x - _lastMousePosition.x;
        this.setLocation(this.getXLocation());
        _lastMousePosition= _currentPoint;
    }    

}

I am stuck at how to move this airplane horizontally when i click on the body, and how to make it move vertically when I click on the wings. I know I use the mouseClicked event, but i think I am messing up inside the methods. Can someone please help me fix this so I am able to move because from few tries, when I click on the body, the plane disappears?
