Need this and everything exactly. Thank you!

We are going to re-do the SuperLottoPlus assignment, and turn it into a Java swing application Create a new class called SuperLottoSwing.java that extends JFrame.

Create the GUI Set the window title to “SuperLottoPlus” (10 point)

Create two JPanel objects (north and center panel) (10 point)

Using BorderLayout, set the position of the north and center panel(10 point)

Add 3 JButtons to the north panel: “I’m Feeling Lucky”, “Reset”, and “Print” (10 point)

Made the north panel background color orange (10 point)

Add a text area box (JTextArea) to the center panel (this is where we will display the lotto numbers) (10 point)

When the user clicks the “I’m Feeling Lucky” button: Make the center panel background yellow (10 point)

Display the SuperLotto lottery numbers in the text area box. (10 point)

When the user clicks the “Reset” button, make the center panel background white, and clear the text. (10 point)

When the user clicks the “Print” button, write whatever text is in the center panel to a file called “superlotto.txt” (10 point)
