The code is

import javax.swing.JOptionPane;

public class Mobile
{
	private String manufacturer;
	private String model;
	private int rating;

	public static void print(Mobile phone)
	{
		JOptionPane.showMessageDialog(null,"Manufacturer: "+phone.manufacturer+"\nModel: "+phone.model+"\nRating: "+phone.rating);

	}

	public Mobile(String manufac, String mdl, int rtg)
	{
		manufacturer = manufac;
		model = mdl;
		rating = rtg;
	}

	public static void main(String[] args)
	{
		Mobile phone = null;

		int choice = 0;

		do
		{

			String input = JOptionPane.showInputDialog("Chose an option:\n1: Input Mobile Details\n2: Print Mobile Details\n3: Quit");

			choice = Integer.parseInt(input);

			switch (choice)
			{
				case 1 :

					String manufacturer = JOptionPane.showInputDialog("Manufacturer:");
