I am having a problem with displaying statement remove or not removed if letter is
r

import java.util.Scanner;
import edu.colorado.nodes.Node;
import edu.colorado.collections.LinkedBag;
import java.util.Iterator;

public class CheeseDemo3
{
public static void showBag(LinkedBag<Cheese> showThisBag, String title)
{


Iterator<Cheese> print;



Cheese printCheese;
System.out.println("\n" + title);
if(showThisBag.size()==0)
System.out.printf("\nEmpty Bag\n");
else
{

print = showThisBag.iterator();
System.out.printf("\n%4s\t%s\n","Type of cheese" , "Exp. year");
while (print.hasNext())
{

printCheese= print.next();
System.out.printf("%4s\t%d\n", printCheese.gettypeOfCheese(), printCheese.getexYear());
}
}
}







public static void main(String [] args)
{

Scanner input = new Scanner(System.in);
LinkedBag<Cheese> myCheeseBag = new LinkedBag<Cheese>();

String letter;
String ch;
int ex;
letter= input.nextLine();


if(letter.equals("s"))



showBag(myCheeseBag, "Bag ");

else if(letter.equals("a"))
{

ch  = input.nextLine();
ex =  input.nextInt();


myCheeseBag.add(new Cheese(ch, ex));
}

else if(letter.equalsIgnoreCase("r"))
 {
	 System.out.println("removed 123");

 ch = input.nextLine();
 ex=  input.nextInt();
 myCheeseBag.remove(new Cheese(ch, ex));
 }




else if(letter.equals("c"))
{
	ch= input.nextLine();
	ex= input.nextInt();
	System.out.println(" num" + myCheeseBag.countOccurrences(new Cheese(ch, ex)));
}
else if(letter.equals("f"))
{
	ch= input.nextLine();
	ex= input.nextInt();
	Cheese myGrabCheese = myCheeseBag.grab();



	System.out.println(myGrabCheese.gettypeOfCheese() + "" +  myGrabCheese.getexYear());
}







while(!letter.equals("x"))
{

letter= input.nextLine();
if(letter.equals("s"))
{

showBag(myCheeseBag, "Bag ");
}
  if(letter.equals("a"))
 {

ch  = input.nextLine();
ex =  input.nextInt();
myCheeseBag.add(new Cheese(ch, ex));
}

 else if(letter.equalsIgnoreCase("r"))
 {

 ch = input.nextLine();
 ex=  input.nextInt();
 myCheeseBag.remove(new Cheese(ch, ex));
 }


 if(letter.equals("f"))
 {

ch= input.nextLine();
ex= input.nextInt();
Cheese myGrabCheese = myCheeseBag.grab();
System.out.println("found :" + myGrabCheese.gettypeOfCheese() + "" +  myGrabCheese.getexYear());

}
}

}
}

Next time, please use the CODE tag instead of upload the file. Also, you should post only the method you are having a problem with...

Anyway in main method, you are implementing 2 sets of if-else statements. One is before the while loop and the other is inside the while loop. From what I understand, you do not need the first set of if-else statement (before the while loop). What you need is the while loop and the inside if-else statement; however, you still need to fix what you really want to do inside it.
