Re: Java - Creating CSV file - adding new entry, editing entries, searching , sorting, display all.

[Jay Maan]

Hi Guys,

Im new to java and this site, please help me if anyone.

Im trying to make a file which includes 3 or more different types of data such as (car, make, and cost).
I have searched many forums and tutorials but seems not very helpful or maybe im not understanding.

My program should enable the user to add new data, edit current, search, sort and display.

Below is so far im trying to do...

import java.io.*;
import javax.swing.JOptionPane;

public class File 
{
	public static void main (String args []) throws IOException
	{
		Object[] selectionValues = {"Add a new object manually", "Search and display details",
				"Edit an object", "Sort the objects", "Display all", "Save objects to a file", 
				"Retreive objects from a file", "Quit"};
	    
		String initialSelection = "Add a new object manually";
		
		Object selection = JOptionPane.showInputDialog(null, "Please select option.",
		"Cars Database Menu", JOptionPane.QUESTION_MESSAGE, null, selectionValues, initialSelection);
		
		JOptionPane.showMessageDialog(null,"You have choosen to " + selection + ".");
		
		if (selection == "Display all")
		{
		final FileWriter outputFile = new FileWriter("Cars.txt");
		final BufferedWriter output = new BufferedWriter(outputFile);
		final PrintWriter printstream = new PrintWriter(output);
		
		String Model[]={"Gallardo", "Mustang", "Skyline"};
		int Cost [] = new int [3];
		Cost[0] = 1000;
		Cost[1] = 100;
		Cost[2] = 10;
		String Make[]={"Lamborghini", "Ford", "Nissan"};
		int i = 0;
		
		for(i=0; i<3; i++)
		{
			printstream.println(Model[i]);
			printstream.println(Cost[i]);
			printstream.println(Make[i]);
		}
		printstream.close();
		
		FileReader inputFile = new FileReader("Cars.txt");
		BufferedReader inputBuffer = new BufferedReader(inputFile);
		
		String line1 = inputBuffer.readLine();
		String line2= inputBuffer.readLine();
		String line3= inputBuffer.readLine();
		
		JOptionPane.showMessageDialog(null, line1 + line2 + line3);
		
		inputBuffer.close();
		System.exit(0);
		}
	}
}

Attached is the output I am getting but I would like to display all 3 cars in each line.
