Hi folks.

I am just learning Java, and am curious as to whether or not you can help me figure something out.

For reference, here is my code:

Code:
import java.text.*;

public class JavaMart3
{
	public static void main (String[] args)
	{


		//Declare and Initialize Variables
		boolean ismore = true;
		String[][] deptCode = new String[13][2];
		String[] itemNum = new String[5];
		String[] itemDesc = new String[5];
		String[] name = new String[25];//To display department name
		String letters;
		String stringConverter; //Used to sort array
		double[] unitPrice = new double[5];
		double doubleConverter; //Used to sort array
		double totalCost = 0;
		int[] itemQuant = new int[5];
		int choice = 0;
		int count = 0; //Count the number of transactions
		int flag = 0;
		int verify = 0;  //Test Variable
		int test = 0; //Test Variable			Both used for searching
		int i = 0;
		int length;
		int intConverter; //used to sort array

		//For Formatting numbers
		NumberFormat cf = NumberFormat.getCurrencyInstance();
		NumberFormat nf = NumberFormat.getNumberInstance();

		//Heading for Program
		System.out.println("\t\t\t\tJavaMart Inventory System");
		System.out.println("\t\t\tProgrammed by Cameron Platt");
		System.out.println("\t\t\tFor Karyn Mart");


		//Load Department Info into array...Can probably be done easier
		deptCode[0][0] = "AU";	deptCode[0][1] = "Automotive";
		deptCode[1][0] = "CO";	deptCode[1][1] = "Cosmetics";
		deptCode[2][0] = "CW";	deptCode[2][1] = "Children's Wear";
		deptCode[3][0] = "EL";		deptCode[3][1] = "Electronics";
		deptCode[4][0] = "FD";		deptCode[4][1] = "Food";
		deptCode[5][0] = "FR";		deptCode[5][1] = "Furniture";
		deptCode[6][0] = "HW";	deptCode[6][1] = "Hardware";
		deptCode[7][0] = "JE";		deptCode[7][1] = "Jewlery";
		deptCode[8][0] = "KB";	deptCode[8][1] = "Kitchen & Bath";
		deptCode[9][0] = "MW";	deptCode[9][1] = "Men's Wear";

The problem lies with deleteing an entry from the array (Selection 3 from the menu.) I have started coding it, but am not quite sure how to complete the code.

I have a slight thought as to what would be needed, but any input from you guys would be appriciated, as I need to have this code done ASAP.

Thanks!
