2. In this lab, you'll practice creating classes and objects, using ArrayList objects, and working with interacting objects (with some nice visuals). Even better, you'll be working with circles, widely considered to be the roundest of all two-dimensional shapes. 1. Import the starter code to begin. Instructions (if needed), for your IDE of choice: a. Jgrasp: i. Download the starter code folder from the website (Download -> Direct download). ii. Extract (unzip) the downloaded folder (right-click -> Extract all). iii. Copy the entire (unzipped) folder to your H: drive; rename it in the usual fashion. b. Eclipse: Circles CS circles ? i. In Eclipse, create a new Java project named in the usual fashion. ii. Download the starter code folder from the website (Download -> Direct download). iii. Extract (unzip) the downloaded folder (right-click -> Extract all). iv. Drag and drop the unzipped materials as follows: 1. Drag the source (*.java) files into the "src" folder. 2. See here for help (don't worry about text files): youtu.be/LOSICIeP6ko int x and int y Create a class Circle.java which is a simple abstraction of an on-screen circle (image). A Circle should (initially) have the following: int radius The center point of the circle's on-screen location. These values represent the circle's (initial) location on screen. The radius of the circle.
