statment replay!!!

[moamen]

Hi Every one,
i'm new to java programming
and while i was trying to make the following programm a problem occured
the problem is that the statment
"Please choose the item you want to buy"
repeats twice every time the loop repeats
so please anyone give me a hand to fix this
thanx

import java.util.Scanner;
public class Store2 
{

	/**
	 * @param args
	 */
	public static void main(String[] args) 
	{
		// TODO Auto-generated method stub
		String item1 = "Adidas shoes";
		String item2 = "Nike shirt";
		String item3 = "Anta wallet";
		String choose = "";
		Scanner input = new Scanner(System.in);
		String dicide = "";
		double total2 = 0;
		int qty1=0;
		int qty2=0;
		int qty3=0;
		double total;
		System.out.printf("We have three items\n1-%s\n2-%s\n3-%s\n\n",item1,item2,item3);
		
		while((!choose.equals("stop")))
		{	
			System.out.print("Please choose the item you want to buy: \n");
			   choose = input.nextLine();
					if((choose.equals("1")))
					{
						System.out.printf("You have chose \"%s\"\n",item1);
						System.out.printf("Are you sure u want to buy \"%s\"?\n",item1);
							dicide = input.nextLine();
							if(dicide.equals("yes"))
							{
							System.out.println("How many pieces you wanna buy?");
								qty1 = input.nextInt();
							System.out.println("the price per piece is $229.88");
							System.out.printf("The total price is: $%.2f\n",total = qty1*229.88);
							total2 = total2 + total;
							}
																	
					}
		}
	}
}

well i dont actually know why, but changing nextLine() to next() in lines 27 and 32 solves the problem. yet i still dont understand why the code above doesnt work properly! :confused:

Before that actually once I looking into your while loop, seems to me it's not quite for other numbers except three items you define. Isn't it?

Read the API specs for the next and nextLine methods to see the difference.

Thanx it worked:D
but i wonder what was the problem in the former code ??:confused:
but thanx very much for your help!!

my loop is just for the three items i defined and the former code is a part of the programme not the whole prog.
i hope i understood you correctely!!!;)
