Write a program that inputs (use JOptionPane.showInputDialog method) four numbers and graphs them as a pie chart. Use class Arc2D.Double and method fill of class Graphics2D to perform the drawing. Draw each piece of the pie in a separate color.

  

Given program (Lab_1_2_start_Up) is an application that allows the user to select a shape from a JComboBox and draws it 20 times with random locations and dimensions in method paintComponent. The first item in the JComboBox should be the default shape that is displayed the first time paintComponent is called. (Screenshot 1 & 2)
