How do I fix this?arrow_forwardI'm learning GUI in my java class and we were asked to do this prompt.(we use netbeans and this assignment was with javafx I believe) Draw 2 circles, with their center x values as half of the scene width, and the first circle’s center y as 1/4 of the scene height, and the second circle’s center y as 3/4 of the scene height. You need to bind the circle center locations to the scene size. My code wasn't running so I just scraped the whole thing. Any help is appreciated. Thank you in advance!arrow_forward
- Motion detection and face detection are computer technologies widely used in a variety of applications related to the digital image. Write a simple Java program to detect faces in a digital image. Use the Haar Cascade library from OpenCV to detect and tag the faces.arrow_forwardUsing java swing coding, you have to 1. Display the list (table) in descending order of points. 2.
