JOptionPane cannot find symbol in module - module

Question

So, the assignment for this week was all about modularization, and the code must contain 6 modules, which is why it looks like a complete mess. Anyway, I'm getting an error that says the module cannot find JOptionPane even though I declared it for the main method. I've posed the code below. Any help appreciated.
Specifically, I'm getting it right here, with this line of code posted at the top.
{ public static String getItemShape ()
{
String typeOfShape;
typeOfShape = JOptionpPane.showInputDialog("Please enter 'C' for a Circle, or 'S' for a Sphere"); //getting input for shape
return typeOfShape; //returning to method
}
}
//This program will find the area or volume of a circle or sphere,
respectively.
import javax.swing.JOptionPane;
public class Java_Chapter_9
{
public static void main(String args[])
{
//Declarations
String itemShape; //type of shape
String runProgram; //user control
Double itemRadius; //radius of tem
Double finalAnswer; //calculation for final answer
//End Declarations
showGreeting (); //Call greeting module
runProgram = JOptionPane.showInputDialog("Please enter 'Y' to run the
program, or 'N' to quit"); //giving user control
while (runProgram.equalsIgnoreCase("y")) //loop for continuous use
{
itemShape = getItemShape (); //calling itemShape module
itemRadius = getItemRadius (); //calling itemradius module
finalAnswer = calculateAnswer (itemRadius, itemShape); //calling the
module for calculation with paramaters
runProgram = JOptionPane.showInputDialog("Enter 'Y' to input more, or
'N' to Quit");
}
showGoodbye ();
}

You have a typo in this line
typeOfShape = JOptionpPane.showInputDialog("Please enter 'C' for a Circle, or 'S' for a Sphere"); //getting input for shape
It should be JOptionPane instead of JOptionpPane. Remove the p
