How to create a moving circle with the Six buttons in the top, (left, right, up, down, shrink, expand buttons) and below in the center moving circle using JavaFX. The moving circle should perform inside of the border only. 1. if you pressed Left Button – it will move to the left until the border of the left side, 2. If you pressed Right Button – it will move to the right until it touches border of the right side, 3. If you pressed Up Button – it will move to the Top until it touches border of the upper side, 4. If you pressed Down Button – it will move to the bottom until it touches border of the lower side 4. If you pressed Shrink Button – it will compress until it becomes dot(.) 5. If you pressed Expand Button – it will Enlarge(increase) until it touches any border or all borders but if it touches the border must stop its expansion. Moreover, the moving circle I need to be created is performing inside the border we created only not outside. please add comments for better understanding since I am a starter in the JavaFx. language Java. Thanks.
