Good Evening, I need help with this Bar Chart Assignment. ADD METHOD and DRAW METHOD are used in this assignment. Instructions and code are below.

Open the BarChart.java file. You need to write code in two different methods: the add method, and the draw method. I have put these two methods at the top of the class for you. There is a lot going on in this class! Don't worry if the rest of the class doesn't make sense, and don't be distracted by the large amount of code in this file. You just need to make 5 changes - let's focus on that. The add Method In the add method, you'll notice three variables created for you: color, name, and value. Perform the following actions: - Add the "color" variable to the "colors" ArrayList (the ArrayList is declared further down in the file - don't worry that you can't see it in this method). - Add the "name" variable to the "names" ArrayList (ditto). - If the "value" variable is 0 or greater, add it to the "values" ArrayList (ditto). - If the "value" variable less than 0 , add 0 to the "values" ArrayList. The draw Method There are two changes to make in the draw method: - You will see a numberOfBars variable declared at the beginning of the method. Currently this variable is set to 0 . Set it to the number of items in the "names" ArrayList. - Inside the if statement, you will see an xmax variable declared. Set this variable to the largest value in the "values" ArrayList. To do this, you will need to loop through the ArrayList and find the largest value. package barchartracerarraylist; import java.awt. Color; import java. awt.

It supports adding a bar (with a specified name, value, and category) and drawing all of the bars to the screen using standard draw. The bars are drawn horizontally (in the order in which they are added from top to bottom) and colored according to the category. The name and value of the bar and drawn with the bar.
